Learn about Cut

Diamond Cut

Diamond cut is a term referring to the style or shape of a diamond, as well as its precise aesthetic proportions. It describes the art and science of transforming a rough diamond into a faceted and polished gemstone with the goal of boosting its beauty and increasing its value. Cut encompasses three primary elements— symmetry, polish, and angle—each of which plays a vital role in determining the quality, value, and brilliance of the diamond.

Diamond Grade

Diamond colour is the absence of colour within a diamond.

Diamond colour evaluation is based on the absence of colour. Diamond colour becomes noticeable when minute particles of trace elements are found inside the lattice structure of diamond. Less trace elements means less colour, meaning more rare, resulting in higher value. GIA’s D-to-Z diamond colour-grading system measures the degree of colourlessness by comparing a stone under controlled lighting and precise viewing conditions to master stones of established colour value.

Learn about Clarity

Diamond Clarity

Diamond Clarity refers to absence of internal inclusions and external blemishes.

Evaluating diamond clarity involves determining the number, size, relief, nature and position of the haracteristics and they affect the overall appearance of the stone. While no diamond is perfectly pure, the closer it comes, the higher the value.

To the naked eye a VS1 and SI2 may look exactly the same but these diamonds are quite different in terms of overall quality and value. This is why expert and accurate assessment of diamond clarity is extremely important by an independent lab such as GIA.
