•Cut is a diamond’s most important characteristic since it has the greatest influence on a diamond’s appearance.
•It has the greatest overall influence on a diamond’s beauty.
•A diamond’s cut grade is an objective measure of a diamond’s light performance, or, what we generally think of as sparkle or glitter.
•Color refers to a diamond’s lack of color, grading the whiteness of a diamond.
•A color grade of D is the highest possible, while Z is the lowest.
(It follows the alphabet without A,B or C)
Color manifests itself in a diamond as a pale yellow. This is why a diamond’s color grade is based on its lack of color. The less color a diamond has, the higher its color grade. Diamonds can also be other colors, such as black, pink, green or blue, but they are uncommon or manufactured.
•Clarity is a measure of the number and size of the tiny imperfections that occur in almost all diamonds.
•Many of these imperfections are microscopic, and do not affect a diamond’s beauty in any discernible way.
Clarity simply refers to the tiny, natural imperfections that occur in all but the finest diamonds. Diamonds with the least and smallest imperfections receive the highest clarity grades.
•Carat is specifically a measure of a diamond’s weight, and by itself may not accurately reflect a diamond’s size.
•We tend to evaluate diamond size by viewing it from the top because that is how diamonds are presented to us when set in a ring.
•To understand diamond size, carat weight should be considered in conjunction with two other criteria: Distance in millimeters across the top of the diamond & cut grade.
~Moissanites have a faint green color when heated, real diamonds do not!
~The easiest way to tell a diamond from any other stone is with a diamond tester. Without one, you either need to invest in gemology courses or visit your local gemologist. If you don’t know of one, your jeweler will certainly know at least a few to recommend!
