If you find yourself in the market for a new diamond, it's wise to know what you are looking at before making the big purchase. The jewelry industry uses the 4 C's, a universal grading system developed by GIA (Gemological Institute of America), to determine the carat, color, clarity and cut of a diamond. Here's what you need to know.
1 Carat = 200 miligrams
1 Point = .01 carat = 1/100 of a carat
Diamonds that appear to be the same size does not mean they are the same weight. The proportions of the cut of the diamond will result in varying weights, effecting the price of a stone. When evaluating a diamond, we will measure the stone and weigh the stone.

The color of a diamond is another contributing factor to the rarity and ultimately the price of the diamond. Each end of the spectrum represents the most valuable diamonds based on color. A completely colorless diamond is rare. A vivid yellow or "fancy" diamond is also rare, and considered valuable for the depth of color. Most diamonds lie somewhere in the middle on the spectrum. A D-J diamond (assuming it has good cut and clarity), will be worth more than S-Y category with the same quality. Color is graded by a jeweler using a master set to compare the diamond's hue.
