A: 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.
