Chances are you already know a lot about diamonds. Diamonds are generally evaluated by assessing the 4 C's: Clarity, Color, Cut, and Carat Weight.

Clarity

Clarity describes the purity of a diamond. This is determined by the number, size, nature, and location of the internal inclusions and external imperfections. The highest purity rating attainable is IF (internally flawless). All of our stones are IF rated.

Color

Color describes the amount of color a diamond contains. The color scale ranges from absolutely colorless (D color) which is the most preferred, all the way down to colors that can be quite gray and muddy looking. In addition to white stones, diamonds can come in some pretty intense colors called "fancy colors" which may be yellow, red, pink, blue, and even green. But when most people think of a diamond, they are thinking of the traditional white diamond. All of our stones are D color.

Cut

Cut speaks to the way a diamond's proportions are created. It is really quite mathematical. A perfectly cut diamond will yield the most fire and brilliance. In the jewelry industry, there is an ideal cut formula which was first developed by Marcel Tolkowsky, a Belgian diamond cutter and engineer who in 1919 developed this optimal cut to bring out the most fire in a diamond.

Carat

Carat is the unit of weight for a diamond. In nature, large diamonds are much rarer than small ones, so they will come with a much higher price tag. A three carat stone may be priced as high as twenty times the price of a one carat stone. Diamond Nexus gemstones are not subject to this issue of size scarcity: all of our stones carry the same per-carat price.
