Loose Diamond Grading

Bookmark and Share

Before a diamond can be deemed suitable for purchasing, the Loose Diamonds are put through extensive tests to determine that it’s authentic prior to receiving a grading certificate. There are several things a Loose Diamond will be graded on, including cut, clarity, color and carat weight. The following guide aims to explain what each of these mean as well as the importance behind Loose Diamond grading.

A well cut Loose Diamond determines how the naked eye views the brilliance of the stone and enables the diamond to reflect light much better than a poorly cut Loose Diamond could. It’s important when choosing a diamond that you never underestimate the importance of the cut. A skilled Loose Diamond cutter can create a work of art with each stone, and regardless of the shape of the diamond a poorly cut stone will leave the diamond dull and lifeless.

With Loose Diamond grading, each stone gets a cut rating ranging from excellent to poor. The height versus depth ratio (referred to as depth percentage) as well as the top of the stone versus the width (the table percentage) are all proportioned by the cut of the diamond. Essentially, the cut is what makes the stone. Proportion, angle and reflection are all important aspects when considering the cut of a Loose Diamond. While each facet of the cut are far above what we can see with our naked eyes, a well-cut stone reflects the utmost in quality and value for the buyer.
