View all FAQsA: A diamond's carat weight refers to the size of the diamond, and is the standard unit of measurement for diamonds. One carat is equal to 200 milligrams, or 0.2 grams. The larger the diamond, the more valuable it is, as larger diamonds are rarer and more difficult to find. However, other factors such as cut, clarity, and color also impact the value of a diamond, and a well-cut diamond of lower carat weight can still be more valuable than a poorly cut diamond of higher carat weight.
A: A diamond's color grade refers to the absence of color in the diamond. The Gemological Institute of America (GIA) uses the following scale to grade diamond color: D (no hue), E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z. The closer a diamond is to the "D" grade, the more valuable it is, as a diamond with no hue is the most rare and desirable.
A: A diamond's clarity grade refers to the presence of internal and external inclusions and blemishes. The Gemological Institute of America (GIA) uses the following scale to grade diamond clarity: Flawless, Internally Flawless, Very, Very Slightly Included (VVS1, VVS2), Very Slightly Included (VS1, VS2), Slightly Included (SI1, SI2), Included (I1, I2, I3). A "Flawless" clarity grade means that the diamond is free of any inclusions or blemishes, while an "Included" grade indicates that the diamond has inclusions and blemishes that are visible to the naked eye.
A: A diamond's cut grade refers to the precise angles, proportions, and finish of a diamond's facets, which determine how well the diamond reflects light and sparkles. The Gemological Institute of America (GIA) uses the following scale to grade diamond cuts: Excellent, Very Good, Good, Fair, and Poor. An "Excellent" cut grade represents the highest level of craftsmanship and light performance, while a "Poor" cut grade indicates that the diamond will have minimal sparkle and fire.
A: Diamonds are valued based on the "Four Cs": Cut, Clarity, Color, and Carat weight. The combination of these factors determines the beauty, rarity, and ultimately the price of a diamond. A high-quality cut maximizes the brilliance and fire of the diamond, while a high clarity grade minimizes inclusions and blemishes. The absence of color is preferred in most diamonds, making a D color grade the most valuable, and carat weight refers to the size of the diamond.
A: Diamonds sparkle due to their unique crystal structure and the way they interact with light. The facets of a diamond reflect and refract light, breaking it into its component colors and creating a brilliant display of light and color. This is known as "fire." The precise cut of a diamond can enhance its ability to sparkle and produce more fire.
A: There are several methods to determine if a diamond is real or fake. One common method is the "spark test," where you observe how the diamond reacts to light and sparkles. Real diamonds will reflect light and sparkle brilliantly, while fake diamonds will appear dull and lack luster. Another method is the "fog test," where you breathe on the diamond and observe how quickly the fog clears. Real diamonds will clear the fog almost instantly, while fake diamonds will take longer to clear. A more reliable method is to have the diamond appraised by a certified gemologist.
A: Yes, diamonds can be found in a variety of colors, including yellow, pink, blue, green, and even red. These colored diamonds are called "fancy colored diamonds" and are even more rare and valuable than clear diamonds. The intensity and saturation of the color determine the value of a fancy colored diamond.
