Despite their hardness, diamonds possess cleavage planes that render them susceptible to chipping under directional force. Moreover, their brilliance can be diminished by surface oils and environmental particulates.

Recommended Care Procedures:

• Routine Cleaning: Clean diamond jewelry regularly using a solution of warm water and a mild, non-abrasive detergent. For deeper cleaning, a few drops of household ammonia may be added. Use a soft-bristled brush (e.g., a worn toothbrush) to gently dislodge debris from beneath the setting. Avoid excessive pressure to prevent damage to the metal prongs.
• Preventive Handling: Remove diamond jewelry during activities involving mechanical stress (e.g., sports, gardening, or manual labor). According to the Gemological Institute of America (GIA), even a minor impact can compromise the setting or chip the stone.
• Chemical Exposure: Apply lotions, perfumes, and hair products prior to wearing diamond jewelry. These substances contain compounds that can form films on the diamond surface and degrade rhodium plating on white gold settings.
• Bathing and Cosmetics: Avoid wearing diamond jewelry in the shower. Soap and shampoo residues can accumulate on the stone, diminishing its optical properties.
• Professional Maintenance: Periodically inspect your jewelry for loose settings. A certified gemologist or jeweler can perform ultrasonic cleaning and secure any compromised mountings.

Gold, a noble metal, is chemically stable but physically soft. Its malleability makes it vulnerable to abrasion and structural fatigue, especially when exposed to chlorinated compounds.

Preservation Guidelines:

• Chemical Avoidance: Remove gold jewelry when using household cleaners or swimming in chlorinated pools. Chlorine can induce stress corrosion cracking, particularly in lower-karat alloys.
• Cosmetic Interactions: Keep gold away from lotions, perfumes, and sanitizers. These can cause surface dulling and interfere with alloy stability.
• Cleaning Protocol: Use warm water and detergent-free soap with a soft brush. For persistent residues, soak briefly before rinsing and drying with a chamois cloth to prevent micro-scratches.
• Restoration: If the jewelry loses its luster, professional steaming and buffing can restore its appearance. Rhodium plating on white or rose gold may wear off over time and can be reapplied by a jeweler.

Platinum is prized for its density and hypoallergenic properties. Though highly durable, it is not immune to surface wear.

Maintenance Recommendations:

• Gentle Cleaning: Clean with warm water and mild soap using a soft brush. Commercial jewelry cleaners may be used, but caution is advised when gemstones are present.
• Scratch Management: Platinum scratches by displacement rather than loss of material. Store separately to prevent contact with harder substances. Polishing can restore its original finish.
• Chemical Safety: Remove platinum jewelry during exposure to harsh chemicals or manual labor to preserve its surface integrity.
• Patina Development: Over time, platinum may develop a matte patina. This is a natural aesthetic evolution and can be polished away if desired.

Proper storage is essential to prevent mechanical damage and preserve aesthetic quality.

• Individual Storage: Store each piece in a fabric-lined box or chamois pouch to prevent abrasion. Avoid placing multiple items together, especially those with diamonds.
• Daily Routine: Jewelry should be the last item worn and the first removed each day to minimize exposure to cosmetics and environmental contaminants.
• Documentation: Keep gemological certificates and insurance documents separate from the jewelry for safekeeping.
• Travel Precautions: Wrap each item individually in soft cloth or padded cases to prevent impact damage during transit.

An engagement ring is both a sentimental and material investment. Its longevity depends on consistent care and mindful handling.

• Handling Technique: Always grasp the ring by its band, not the stone or setting, to avoid loosening the mount and transferring oils to the diamond.
• Storage: Store separately in a rigid jewelry box. Avoid soft pouches, which offer insufficient protection against impact.
• Activity Restrictions: Remove the ring during manual tasks and exposure to chemicals. This prevents structural stress and surface contamination.
• Insurance: Secure comprehensive insurance to protect against loss, theft, or accidental damage.
• Professional Inspection: If the stone appears loose or misaligned, consult a certified jeweler immediately. These evidence-based practices, grounded in gemological and metallurgical principles, will help preserve the integrity and beauty of your fine jewelry for generations.

Each diamond shape has its own unique characteristics that influence its overall quality and appearance. The best shape for you depends on your personal style and the design of the jewelry you’re envisioning. Our seasoned experts are here to guide you in selecting the ideal solitaire that suits your taste and occasion.

Round

The round brilliant-cut diamond is the most popular shape worldwide, making up over 75% of all diamond sales. For nearly a century, diamond cutters have refined this shape using advanced light theories and precise mathematics to maximize its fire and brilliance. If you're looking for timeless sparkle, the round diamond is a classic choice.

Princess

Second only to the round in popularity, the princess cut is especially beloved in Europe. Its sharp corners and square shape give it a modern, elegant look. Known for its dazzling brilliance, it's a top pick for engagement rings. For optimal symmetry, choose a princess diamond with a length-to-width ratio between 1.00 and 1.05.

Emerald

The emerald cut features a rectangular, step-cut design with fewer facets, which can make inclusions and color more noticeable. Its clean lines offer a sophisticated, vintage appeal. For a classic emerald shape, aim for a length-to-width ratio between 1.30 and 1.40.

Aascher

Similar to the emerald cut but square in shape, the Asscher cut offers a unique, art-deco flair. Its ideal length-to-width ratio falls between 1.00 and 1.05, ensuring a balanced and symmetrical appearance.

Marquise

With its elongated body and pointed ends, the marquise cut creates the illusion of a larger diamond by maximizing carat weight. For a traditional marquise look, choose a length-to-width ratio between 1.75 and 2.25.

Oval

Oval diamonds combine the brilliance of a round cut with an elongated shape that flatters the hand, especially for those with shorter fingers. A length-to-width ratio between 1.35 and 1.65 offers the most balanced appearance.

Radiant

Radiant-cut diamonds feature trimmed corners and a cuboid shape, making them versatile for various jewelry styles. For a square radiant cut, look for a ratio between 1.00 and 1.05. Prefer a rectangular look? Choose a ratio above 1.25.

Pear

Also known as the teardrop cut, the pear shape blends a rounded end with a pointed tip. Its unique silhouette is popular for earrings, pendants, and rings. An elongated pear shape can subtly elongate the fingers for a graceful look.

Heart

The heart-shaped diamond is a romantic symbol of love and affection. Its distinctive shape makes it perfect for meaningful gifts and special occasions. Ideal length-to-width ratios range from 0.90 to 1.15 for a well-proportioned heart.

Cushion

Known as the “pillow cut,” the cushion diamond has rounded corners and a soft square or rectangular shape. It’s been a favorite for over a century. For a square cushion, aim for a ratio between 1.00 and 1.05; for a rectangular look, go above 1.25.

Baguette

The baguette cut is a sleek, elongated shape with straight edges and step-cut facets. Often used as side stones or accents, baguette diamonds offer a minimalist, elegant touch to any jewelry piece.

Carat refers to the weight of a diamond, not its size. As carat weight increases, so does the price—often exponentially. For example, a 2-carat diamond of the same quality will cost significantly more than a 1-carat diamond. Don’t confuse “carat” with “karat,” which measures gold purity.

• 1 carat = 100 points (e.g., 0.75 carat = 75 points)
• 5 carats = 1 gram
• 1 carat = 0.200 grams

What Carat Weight Should I Choose?

Your ideal carat weight depends on your budget and preferences. While larger diamonds are more noticeable, beauty isn’t just about size. Cut, color, and clarity are equally important. You might opt for a smaller, higher-quality diamond or a larger one with lower grades—both can be stunning depending on your priorities.

Once you’ve chosen your desired cut, color, and clarity, it’s easier to find a carat weight that fits your budget. Visual guides can help you understand how different carat sizes appear when worn.

Expert Tips from G.Eager Jewels

• Always check the millimeter (mm) measurements of a diamond—this reflects how large it will look when set in jewelry.
• Diamond prices spike at full and half-carat marks (e.g., 0.50, 1.00, 1.50). Choosing a diamond just below these weights can offer better value with minimal visual difference.
• Finger size affects perception: a 1.50-carat diamond looks larger on a size 8 finger than on a size 12.

When evaluating diamond color, experts actually assess how colorless a diamond is. The less color present, the higher the quality and value. While most diamonds appear white, many contain subtle tints that can affect their appearance and price. These color differences are often invisible to the untrained eye but play a crucial role in grading.

Diamonds are graded on a scale that measures the absence of color—the clearer the diamond, the more valuable it is.

GIA Color Grading Scale

The Gemological Institute of America (GIA) developed a standardized scale ranging from D to Z:

• D: Completely colorless and extremely rare—highest value.
• E–F: Nearly colorless, with minute traces of color detectable only by experts.
• G–J: Near colorless, offering excellent value with minimal visible tint.
• K–Z: Noticeable color, typically yellow or brownish hues.

Each letter represents a range of tone and saturation, helping buyers make informed choices.

Which color to choose?

• Colorless vs. Near Colorless: The visual difference is minimal, but the price gap can be substantial.
• D–F Range: Ideal for those seeking perfection and purity.
• G–I Range: Offers great value while maintaining a colorless appearance.
• J–L Range: Suitable for larger diamonds or higher clarity within budget.
• Shape Considerations: Fancy shapes like marquise, radiant, pear, and princess can concentrate color at their tips—opt for higher color grades in these cases.

Fluorescence

Fluorescence refers to a diamond’s reaction to ultraviolet (UV) light, often seen in environments like nightclubs. While usually invisible under normal lighting, strong fluorescence can give diamonds a milky or oily appearance, reducing their value.

However, fluorescence can enhance the appearance of yellow-tinted diamonds (J–M range), making them look whiter. In such cases, diamonds with faint to medium fluorescence may offer better visual appeal and value.

Tips from g.Eager jewels experts

• Metal Matters: Yellow gold can reflect color into the diamond—consider I or lower grades. For white gold or platinum, F–H grades are ideal.
• Grade Differences: The jump from G to H or I to J is subtle to the eye but significant in cost. More noticeable differences occur between D and G or G and J.
• Size Sensitivity: Larger diamonds (1.50ct+) show color more clearly—choose higher grades accordingly.
• Fluorescence Advantage: In J–M color ranges, fluorescence can make diamonds appear whiter.

Clarity measures a diamond’s internal (inclusions) and external (blemishes) characteristics. These natural features affect how light passes through the diamond, influencing its brilliance.

Most imperfections are microscopic and don’t impact beauty. However, larger or darker inclusions—like black “Natts”—can be visible and reduce value.

GIA Clarity Grades

Grade	Description
FL	Flawless – No inclusions or blemishes under 10x magnification. Extremely rare.
IF	Internally Flawless – No inclusions, only minor surface blemishes. Very rare.
VVS1/VVS2	Very Very Slightly Included – Inclusions are extremely difficult to detect.
VS1/VS2	Very Slightly Included – Minor inclusions, invisible to the naked eye.
SI1/SI2	RVery Slightly Included – Minor inclusions, invisible to the naked eye.
I1/I2/I3	Included – Obvious flaws that can affect brilliance and transparency.

What clarity grade to choose?

• VVS1/VVS2: Ideal for those seeking near-perfect diamonds.
• VS1/VS2: Great value—clean to the naked eye.
• SI1/SI2: Budget-friendly options for larger size or better color.
• Eye-Clean Diamonds: SI1 and VS2 often appear flawless without magnification.

Keep in mind: As diamond size increases, inclusions become more noticeable. A 2.00ct SI2 will show flaws more easily than a 0.30ct SI2.

Tips from g.Eager jewels experts

• Under 1ct: Clarity is less critical—price differences are smaller.
• 1–2ct Range: SI1 or better ensures minimal visible inclusions.
• Over 2ct: VS2 or higher is recommended to avoid visible flaws.
• Shape Sensitivity: Asscher and Emerald cuts reveal inclusions more easily—choose SI1 or better.

Cut is the only diamond characteristic shaped by human craftsmanship. It determines how well a diamond reflects light—affecting brilliance, fire, and sparkle. A well-cut diamond appears vibrant and lively, while a poorly cut one may look dull.

Cut includes proportions, polish, and symmetry. For round diamonds, all three are graded. For fancy shapes, only polish and symmetry are assessed.

Cut grades

Grade	Description
Ideal/Excellent	Reflects nearly all light—maximum brilliance and beauty.
Very Good	Reflects most light—great value.
Good	Adequate light reflection—budget-friendly.
Fair	Less brilliance—still a quality diamond.
Poor	RVery Slightly Included – Minor inclusions, invisible to the naked eye.

Which Diamond Cut Grade Should You Choose?

The cut grade is the most critical factor in determining a diamond’s overall beauty. Even a diamond with top-tier clarity and color can appear lifeless if it’s poorly cut. On the other hand, a well-cut diamond—even with slightly lower color (G-H) or clarity (SI1-SI2)—can still look stunning due to its ability to reflect light and create brilliance.

Recommended Cut Grades

• For Maximum Sparkle: Choose a round diamond with a cut grade of Very Good or Excellent, and ensure the Polish and Symmetry grades are at least Good, ideally Very Good.
• For Fancy Shapes: Avoid diamonds with Polish or Symmetry grades below Good.
• For Top Quality: Look for a Triple Excellent diamond—graded Excellent in Cut, Polish, and Symmetry.
• For Budget Buyers: If size is your priority, a diamond with a Good or Fair cut may be acceptable. It won’t sparkle as much, but you’ll get a larger stone for the same price.

Common Pitfalls to Avoid

• Uncertified Diamonds: Be cautious—uncertified diamonds can be misleading in quality.
• Deep Cuts: Avoid diamonds that are cut too deep. These hide carat weight in depth rather than width, making them appear smaller than they actually are. For example, a 1.00 carat diamond may look like a 0.90 carat if it’s too deep.
• Trusted Certification: Always buy diamonds certified by reputable labs such as GIA, IGI, HRD.

Expert Tips from G.EAGER JEWELS

• Prioritize Cut: Since cut affects beauty the most, balance your budget across Carat, Color, and Clarity to afford a diamond with an Excellent or Very Good cut.
• Avoid Poor Cuts: Even if cheaper, a poorly cut diamond is not recommended. If budget is tight, opt for slightly lower color or clarity—but maintain a cut grade of Good or better.

• Brilliance: The brightness created by white light reflecting from the diamond’s surface and interior.
• Contrast: Light and dark areas caused by the cut or shadows—these are not flaws but part of the diamond’s visual depth.
• Scintillation: Sparkles seen when the diamond moves. These flashes are strongest under bright, multi-directional lighting.
• Fire: Colored flashes caused by light dispersion. More visible in darker settings and more vivid in colorless diamonds.

Key Diamond Terminology

Term	Definition
Diameter	Width across the diamond at the girdle.
Table	Largest facet on the top of the diamond
Crown	Top portion from the table to the girdle
Girdle	Widest edge where crown meets pavilion
Pavilion	Lower portion from girdle to culet
Culet	Small facet at the bottom tip
Depth	Total height from table to culet

Diamond Proportions

Diamond proportions refer to the size, shape, and angles of each facet. These determine how well the diamond interacts with light:

• Pavilion Angle: Must be precise—too shallow or deep causes light leakage and dullness.
• Crown Angle: Influences how light enters and exits the diamond.
• Depth %: Depth divided by diameter. Shallow diamonds have low depth %, deep ones have high depth %.
• Table %: Size of the table relative to the diameter—affects light performance.

Symmetry

Symmetry ensures that all facets are evenly aligned. Poor symmetry can distort the diamond’s shape and reduce brilliance, fire, and scintillation. Common issues include:

• Off-center culets
• Misshapen facets
• Round diamonds that aren’t truly round.

Polish

After cutting, each facet is polished. Poor polishing leaves behind scratches or streaks, similar to marks after waxing a car. An Excellent Polish means the diamond has minimal or no visible surface marks.

Diamonds are evaluated based on the 4Cs:

• Color
• Clarity
• Cut
• Carat weight

To ensure accuracy and consistency, grading is conducted by independent gemological laboratories such as:

• GIA(Gemological Institute of America)
• IGI(International Gemological Institute)
• HRD(Hoge Raad voor Diamant)

At G.Eager Jewels, we exclusively offer diamonds certified by GIA, IGI, and HRD, and our diamond jewelry is graded by IGI and HRD. While other labs do exist, not all maintain the same rigorous standards. Some may be more lenient in their evaluations, which can affect the reliability and reputation of their grading.

Understanding Diamond Grading Nuances

Every diamond is unique, making it challenging to fit into rigid grading categories. For example:

• A diamond labeled SI1 clarity actually falls within a spectrum—from the highest quality SI1 to the lowest.
• The same applies to Color grades, which also span a range within each category.

At G.Eager Jewels, our team includes certified gemologists with extensive industry experience. Every diamond is carefully assessed by our experts and cross-verified with the official lab grading report to ensure accuracy and transparency.

Certified vs. Uncertified Diamonds

Certified Diamonds

A certified diamond comes with a grading report issued by an accredited gem lab. This report confirms that the diamond has been independently evaluated and meets the specifications listed.

Benefits include:

• Assurance of quality and authenticity
• Legal documentation of the diamond’s characteristics
• Confidence in the diamond’s value and pedigree

Uncertified Diamonds

An uncertified diamond lacks a formal grading report. Its quality is based solely on the seller’s description.

Key points to consider:

• It may still be beautiful and valuable
• Without certification, you must trust the seller’s expertise
• If you're not experienced in diamond evaluation, this can pose a risk

Gold (chemical symbol: Au) is a noble metal with a rich historical and cultural legacy. Its distinctive yellow hue, high malleability, and resistance to oxidation and corrosion make it uniquely suited for ornamental and monetary use. Gold does not react with oxygen or most acids, which accounts for its enduring luster and stability over millennia.

Physical and Chemical Properties

• Malleability and Ductility: Gold is the most malleable and ductile of all metals. A single gram can be beaten into a sheet covering one square meter.
• Corrosion Resistance: As a noble metal, gold resists tarnishing and rust due to its low reactivity.
• Color: Its yellow coloration arises from relativistic effects in its electron structure, a phenomenon unique among metals.

Purity and Karat System

Pure gold (24 karats) is too soft for practical use in jewelry. To enhance its mechanical strength, it is alloyed with other metals such as copper, silver, nickel, and zinc. The karat system quantifies purity as follows:

Karat	Gold Content	Suitability for Jewelry
24k	100%	Too soft
22k	91.7%	Limited use
18k	75.0%	Ideal for fine jewelry
14k	58.3%	Durable and popular
10k	41.7%	Generally not preferred

Alloying and Color Variations

The color of gold alloys depends on the type and proportion of secondary metals:

• Yellow Gold: Achieved by alloying with copper and silver. The warm tone reflects traditional aesthetics and is often associated with wealth and prestige.
• White Gold: Created by alloying with palladium, nickel, or silver, and typically plated with rhodium for enhanced brightness and durability.
• Rose Gold: The pink hue results from a higher proportion of copper. While visually appealing, it may be less suitable for daily wear due to its relative softness.

Hallmarking Standards

In accordance with international hallmarking protocols such as the Vienna Convention, gold jewelry may be certified for purity and authenticity. In Europe, hallmarking is regulated under the Bureau of European Standards Act (1986). A hallmark typically includes:

• Fineness number (e.g., 750 for 18k)
• Assay center identification
• Jeweler’s mark
• Year code (alphabetical)

Laser engraving and punch marking are standard techniques for hallmark application, ensuring traceability and consumer confidence.

Platinum (chemical symbol: Pt) is a dense, ductile, and highly corrosion-resistant transition metal. Its silvery-white appearance and exceptional durability make it a preferred choice for high-end jewelry and industrial applications.

Material Characteristics

• Density: Platinum is nearly twice as heavy as gold, contributing to its substantial feel.
• Durability: Despite its softness, platinum is highly resistant to wear and chemical attack.
• Purity: Jewelry-grade platinum typically contains 95% pure platinum, alloyed with iridium or ruthenium to enhance hardness.

Applications in Jewelry

Platinum’s neutral color and structural integrity make it ideal for securing gemstones, especially diamonds. Unlike gold, it does not wear away over time, ensuring long-term stability of stone settings.

Hypoallergenic Properties

Due to its high purity and inert nature, platinum is hypoallergenic and suitable for individuals with sensitivities to nickel or other common alloying metals.

Economic and Industrial Value

Platinum is rarer than gold and commands a higher market value. Beyond jewelry, it is critical in catalytic converters, electronics, and medical devices, underscoring its industrial significance.

What Is a Carat?

A carat is a unit of weight used to measure diamonds and other gemstones. It does not indicate size, although many people mistakenly equate the two. The term originates from carob seeds, which ancient gem traders used as counterweights due to their uniform mass.

• 1 carat = 200 milligrams (0.2 grams)
• Carats are subdivided into 100 points, allowing precise measurement to the hundredth decimal place. For example:
  • 0.25 carats = 25 points
  • 0.10 carats = 10 points (often called “10 cents” in trade slang)

Carat vs. Karat

Don’t confuse carat (diamond weight) with karat, which refers to the purity of gold. They sound similar but measure entirely different properties.

While carat weight affects a diamond’s value, it doesn’t directly determine its visible size. The cut quality, shape, and depth of a diamond significantly influence how large it appears.

• A 1.00 carat round brilliant typically measures 6.4–6.5 mm in diameter
• A 2.00 carat diamond may not look twice as large as a 1.00 carat due to how weight is distributed within the stone

Diamonds with poor cuts may carry more weight below the surface (in the pavilion), making them appear smaller than well-cut stones of the same carat weight.

Diamond prices increase exponentially with carat weight due to rarity. For example:

• A 2.00 carat diamond can cost significantly more than twice the price of a 1.00 carat diamond, even if other quality factors (cut, color, clarity) are equal

This is because larger diamonds are rarer and more desirable, especially at “magic sizes” like 1.00, 1.50, and 2.00 carats.

Round Brilliant Diamonds (Approximate Diameter)

Carat Weight	Diameter (mm)
0.25 ct	~4.1 mm
0.50 ct	~5.2 mm
0.75 ct	~5.8 mm
1.00 ct	~6.4–6.5 mm
1.50 ct	~7.4 mm
2.00 ct	~8.2 mm

Note: These measurements assume an “Excellent” cut. Variations occur due to differences in cut proportions and depth.

When set in a ring, diamonds often appear 10–15% larger due to the surrounding metal and design. Finger size also affects perception:

• On smaller fingers, even modest diamonds can look bold
• On larger fingers, the same diamond may appear more delicate
