Precious stones come in virtually all colors of the rainbow, from the “beautiful violet” of the Hope diamond to shades of blue, brown, overcast, orange, etc . But colored diamonds are very rare in addition to precious. Chances are, all the diamonds you’ll see in your diamond video editing will be white or yellow, and the whiter the better.
The very yellow color in diamonds comes from nitrogen, and as a new rule, the more yellow the stone, the less valuation it has. There’s a good reason for this. The yellower the gem, the less sharp and sparkly it appears. A white in color stone lets lighter pass through it, making it sparkle plus shine.
The exception to the rule is the canary wedding, which is a beautiful bright yellow and very expensive. Some people are definitely sensitive to the color of diamonds. What may appear slightly yellowish to you may look clear to another person, so it requires a higher color grade to satisfy you.
The best way to judge bedroom of a diamond is to use either a Gran Fall Spectrum Colorimeter by Gem Instruments or compare it to a excel at set.
HERE’S THE COLOR GRADING SCALE:
D, E, P refers to colorless and G, H, I refers approximately to colorless, J, K, L indicated slightly discolored, M, N, O shows light yellow P, Q, R, S, T, U, V, W, X illustrates darker yellow and Z to Fancy colors.
Despite the fact there are several grades in each category, there are slight discrepancies between the letter grades. D is the clearest and most worthwhile, X is a dingy yellow and least expensive. Z grade-colored diamonds are the rarest and most expensive. A diamond for that reason saturated with nitrogen that it becomes a deep, rich orange is as rare as a colorless diamond.
FLUORESCENCE
Fluorescence is known as a diamond’s reaction to ultraviolet (UV) light. Some diamonds ambiance in different colors under UV light, and the general leadership is to avoid them. If you put a diamond under UV light and it glows strong blue, the diamond could possibly look dull in the sunlight. Diamonds with strong fluorescence may be worth up to 20% less than diamonds which do not fluoresce. Faint fluorescence which doesn’t fog the diamond is ACCEPTABLE.
CORRESPONDING GRADING
Corresponding grading means matching clarity degrees with color grades. For every clarity grade, there’s a colors grade that corresponds, or makes the best match on determining value. Diamonds that have corresponding grading sell just for higher prices originally and they also appreciate in value above diamonds that don’t, and therefore have higher resale cost. Buying a diamond with non-corresponding clarity and color quality grades is like buying a pink Porsche: it’s okay as long as you do try to resell it. The market for pink Porsches is just not as good as the market for, say, red Porsches.
The value of your stone is always based on the lowest clarity or color standard and its highest corresponding grade. When you don’t correspond the very grades – say you buy high clarity and decreased color, or high color and low clarity instant you’ll never get your money back for the higher grade.
