Diamond Classification





THE 4 C's TO DIAMOND CLASSIFICATION
The 4 Cs of Diamonds include: Cut, Color, Clarity, and Carat Weight

	CUT
	-THE IDEAL CUT When a round brilliant diamond has been cut to "Ideal" proportions by a master cutter, it is a splendor to behold. The Ideal Cut Diamond describes a round brilliant diamond that has been cut to exact and mathematically proven proportions. Its symmetry, with 58 exactly placed facets, produces the ultimate in lustre and beauty. When a diamond is cut to the ideal proportions, all the light entering from any direction is totally reflected through the top and is dispersed into a display of sparkling flashes and rainbow colors.
	-PREMIUM CUT A Premium Cut diamond demonstrates subtle variations from the Ideal Cut. Although dimensional differences affect a diamond's reflection of light, a Premium Cut still achieves a harmonious balance between it's proportions and the display of brilliance.
	-INFERIOR CUT Most diamonds are "spread" in their cutting to retain maximum weight from the original rough. A heavier diamond will result, but at a dramatic sacrifice of potential fire and brilliance.
	COLOR
	Most diamonds, although appearing colorless, actually have slight tones of yellow or brown. As these tones become more easily apparent, the rarity and the cost decrease.
	Color Grading Scale- consists of a grading scale from D-Z
	CLARITY
	Practically all diamonds contain naturally occurring internal characteristics called inclusions. The size, nature, location and amount of inclusions determine a diamond's clarity grade and affects its cost. One unique advantage of the Ideal Cut is that its sparkle can mask otherwise noticeable inclusions
	CARAT WEIGHT
	The weight of a diamond is measured in carats. One carat is divided into 100 parts called "points," 1 CT = 1.00; 1/2 CT = 0.50. The value of two diamonds of the same weight can vary greatly depending on the color, clarity and especially the cut.
