The strength of Color is the most important factor in determining the value of a champagne diamond. Argyle Diamonds has devised the C1 to C7 color scale to grade champagne diamonds.
Gemologists use three terms to describe color:
Hue: the dominant color of the diamond. Sometimes, modifying colors or tints can affect the hue of a diamond.
Tone: the amount of lightness or darkness in the diamond. The range of tone extends from light to dark.
Saturation: the strength or intensity of color in the diamond. The saturation of light in diamonds can vary from pastel to vivid and intense. The darker and more intense the color, the rarer and more expensive the diamond.
While the darker and rarer cognac diamonds are the most expensive, the beauty and value of champagne diamonds ultimately remains in the eyes of the beholder. After all, the appeal of color is entirely dependent on one’s personal preference and taste. With a palette for all skin tones, you will find the champagne diamond that lets you expresses your mood and individuality through color.
Clarity
Diamonds form under tremendous heat and pressure, making it extremely rare to find a diamond that lacks any internal and external characteristics. These characteristics are a by-product of its formation and help gemologists to identify individual stones and to distinguish natural diamonds from synthetics and simulates.
Gemologists use a scale to describe the clarity of diamonds.
Cut
A polished diamond’s beauty lies in how light interacts with its facets, refracting, transmitting and reflecting rays, which are ultimately captured by your eyes. The result is a magnificent display of three attributes:
Brightness: the combination of all light reflecting from the surface and interior of the diamond.
Fire: the ‘flares’ of color emerging from a diamond.
Scintillation: the flashes of light seen when a diamond, the light source or the observer moves.
Diamonds with fine proportions, symmetry and polish optimize their interaction with light and have increased brightness, flare and scintillation.
Carat weight
Carat is standard unit of weight for diamonds. One carat equals 0.2 gram in weight and 100 points equals one carat. Hence, 0.75 carat = 75 points; ½ carat = 50 points.
