What is that sparkler inside your stocking? A surprise? Could it be an engagement ring? It’s that time of year for giving and a popular time for engagements. Some of us will be stunned and some of us will have the option of picking the stone out ourselves. Either way it is important to educate yourself and your future fiancée before your engagement diamond is purchased. What kind of style or shape of stone is perfect for you? Here are some tips to keep in mind when purchasing a diamond.
The 4 C’s
Color describes the amount of color the diamond contains. This can range from colorless to yellow with slight tints of yellow, gray or brown.
Cut refers to the proportions, finish, symmetry, and polish of the diamond. These factors determine the fire and brilliance of a diamond. Well cut diamonds sell at a premium and poorly cut diamonds sell at discounted prices. With the advent of technology, the cut of the diamond can be determined through the use of the Dia-Mension system, a computerized system which takes accurate measurements and proportions of a diamond in seconds, in addition to the standard millimeter gauge.
Carat is the unit of weight for all gemstones. One carat is subdivided into 100 “points”. Therefore a diamond measuring 75 points is 3/4 carat in weight, or 0.75ct. There are five carats in a gram. The word “carat” comes from the seed of the carob tree pod which is found in tropical climates. These seeds were used until this century to weigh precious gems.
A diamond’s clarity is determined by the number, nature, position, size and color of internal characteristics called “inclusions” and surface features called “blemishes”. These irregularities occurred in the liquid magna (volcanic rock) within which the diamond was created. Clarity is measured on a scale ranging from pure (flawless) to heavily included (I-3). The clarity of a diamond is graded by using 10X magnification under good lighting by an experienced grader. The final clarity grade is usually determined by how easy the inclusions and blemishes are for the grader to see.
