Choosing the Right Diamond
For most people, buying a diamond is a new experience, but that doesn’t mean it should be overwhelming. Understanding a diamond’s quality characteristics is straightforward and simple. The Jillian’s Cut Diamond education is designed to answer all of your questions. This section will give you insight on diamond characteristics, which of these are most important, and how these characteristics influence the overall appearance of your ideal diamond.
In just a few minutes you’ll know everything you need to find your perfect diamond. Diamonds are born deep within the earth, where tremendous heat, pressure, and time set the stage for a dazzling display. Once the rough stones emerge, they are literally transformed by imagination and artistry. The result is both rare and remarkable: exceptional beauty that captures the eye and the heart. Each diamond is completely unique. Its individual characteristics – even those that are subtle can impact its visual appeal and value. A reliable gemological report can provide a clear basis for comparison.
A carat is a unit of metric measurement used for gems. One carat (ct.) equals 100 points, 200 milligrams, or 1/5
of a gram.
Clarity is measured by 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. Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called ‘inclusions’ and external characteristics called ‘blemishes.’ Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. While no diamond is perfectly pure, the closer it comes, the higher its value.
The diamond color evaluation of most gem-quality diamonds is based on the absence of color. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. Diamond color-grading systems measure the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to master stones of established color value. The scale begins with the letter D, representing colorless, and continues, with increasing presence of color, to the letter Z.
A diamond’s cut grade is based on the combined analysis of its proportions, polish, and symmetry factors that determine the way light interacts with the stone. The most preferred stones are graded on a scale from very good to excellent. Some perfect stones achieve a particularly precise and romantic “Hearts & Arrows” pattern that reveals a circle of hearts through the pavilion and arrows through the crown.
