The shape of a diamond refers to its physical form when viewed from above. Popular shapes include round, oval, princess, cushion, pear, and emerald. Each shape affects the diamond’s brilliance, perceived size, and overall aesthetic. Round diamonds offer maximum sparkle, while elongated shapes like oval and marquise can make fingers appear longer. Choosing the right shape depends on personal preference, style, and how the diamond will be set in jewelry.
Carat weight measures a diamond’s size, with one carat equal to 0.2 grams. While carat influences a diamond’s price, it’s not the only factor in beauty. A well-cut diamond may appear larger than a heavier diamond with a poor cut. Additionally, different shapes distribute weight differently, affecting how large the diamond looks when worn. When choosing carat weight, consider both visual impact and budget.
The price of a diamond is determined by multiple factors, including carat weight, cut, color, clarity, and certification. Larger diamonds or those with higher quality grades tend to be more expensive. Market demand and rarity also impact price. When selecting a diamond, it’s essential to balance budget with desired attributes. Comparing certified diamonds with similar specifications helps in finding the best value without compromising on beauty or brilliance.
Polish affects how smooth a diamond’s surface is, which can influence both brilliance and color appearance. A well-polished diamond allows for better light reflection, enhancing its visual appeal. While fancy color diamonds prioritize color over sparkle, excellent polish ensures that the diamond looks vibrant and luminous. Look for diamonds with Excellent or Very Good polish grades for the best results.
The cut of a fancy color diamond is designed to enhance its hue rather than maximize brilliance. Unlike colorless diamonds, where sparkle is the priority, fancy color diamonds are cut to deepen and intensify their natural color. This means the ideal cut proportions may differ from standard cut grades. Shapes like cushion and radiant are often preferred because they emphasize color saturation while still providing sparkle.
Symmetry plays an essential role in ensuring even light distribution across a fancy color diamond. Precise facet alignment enhances the stone’s overall appearance, helping to maintain its color intensity and brilliance. While some asymmetry is tolerated in fancy color diamonds to maximize color, choosing a diamond with a Very Good or Excellent symmetry grade ensures a well-balanced, visually appealing gem.
Unlike colorless diamonds, fancy color diamonds are prized for their rich and vibrant hues. Their color is graded based on three factors: hue (the dominant color, such as pink, blue, or yellow), tone (lightness or darkness), and saturation (intensity). The most valuable fancy diamonds have vivid, evenly distributed color with no visible undertones. Lab-grown fancy color diamonds offer the same captivating colors at a more accessible price, making them an excellent choice for those seeking unique and vibrant gemstones.
The table percentage in fancy color diamonds influences how color is distributed across the stone. A smaller table can concentrate color intensity, while a larger table may allow more light leakage, potentially softening the hue. Different fancy shapes have unique ideal table percentages that enhance their specific color and brilliance balance.
Fancy color diamonds are graded for clarity like colorless diamonds, but inclusions are often less critical due to their deep hues. Since strong colors can mask minor inclusions, clarity is less of a determining factor in value. However, diamonds with fewer visible inclusions are still more desirable. When selecting a fancy color diamond, prioritize color intensity first, followed by clarity and cut.
A Triple Excellent (3EX) grade in fancy color diamonds signifies the highest ratings in Cut, Polish, and Symmetry. While cut grades for fancy color diamonds focus on maximizing hue rather than brilliance, a 3EX rating ensures superior craftsmanship. This guarantees the diamond’s proportions, surface quality, and facet alignment contribute to its best possible color and visual impact.
Depth percentage is crucial in fancy color diamonds because it affects how color is reflected and perceived. Deeper cuts may intensify color, while shallower cuts can lighten the hue. The optimal depth varies based on the diamond’s shape and the desired color effect. Expert cutting ensures the best balance of color richness and overall appearance.
Fluorescence refers to how a diamond reacts to UV light, often creating a soft glow. In fancy color diamonds, fluorescence can impact color perception—sometimes enhancing vibrancy or, in rare cases, making the diamond appear hazy. For certain hues, such as blue or yellow, fluorescence may positively influence the stone’s color intensity. Always review how fluorescence affects the specific diamond’s appearance before purchasing.
Ratio is particularly important for fancy shapes like emerald, oval, and pear-cut diamonds, influencing both appearance and color. In fancy color diamonds, a slightly elongated or deeper shape can enhance color concentration. Choosing the right ratio depends on aesthetic preferences and how the diamond will be set in jewelry.
