Origin of the Diamond 4Cs

Every diamond is a miracle of time and place and chance. Like snowflakes, no two are exactly alike.

The Finish of a Diamond

The finish on a diamond is more of an aesthetic term rather than a term that would change the value of a diamond. The finish just refers to the polish on the external part of the stone. Most diamonds that you will buy will already have a polished finish to them to give them the sparkle and clean look that you would want in a stone. Diamonds are essentially created for the commercial market, so you everything from mining, to cleaving, to setting it on your ring is done to make the stone more aesthetically beautiful. This is what polishing achieves, when it is well cut and polished, it is said to have a beautiful finish.

Diamond Polish

To polish a diamond is exactly as it sounds. You take a rough stone that has been set and start the process of rubbing the stone to make it smooth and shiny, as well as reducing any appearance of flaws or imperfections. The polish effects the way the light is able to pass through the diamond, and influences the look of the diamonds brilliance.

Understanding the Clarity Grade of Your Diamond

Gem-quality diamonds are evaluated and graded by their clarity, the absence of naturally occurring internal flaws, called Inclusions, and external flaws, called Blemishes. Inclusions and Blemishes, whether visible to the naked eye or only under a 10X microscope, can interfere with a diamond’s ability to optimally reflect light, thus reducing the diamond’s brilliance, fire and scintillation. More importantly, flaws impact beauty and desirability; there is much greater demand for a diamond with no flaws or very few flaws.
