Diamond Clarity

Clarity is a measure of a diamond's internal flaws. Because diamonds are formed in nature, the great majority of them contain microscopic inclusions such as bubbles, spots, lines or feathers - markings that make every diamond unique and identifiable. In fact, diamond-grading certificates include a "plot" of inclusions that can be used to identify the diamond. So long as these inclusions are small in size and do not hamper the diamond's ability to reflect light, they will not affect its beauty. In fact, most inclusions cannot be seen by the naked eye.

Diamond Color

Discussion of a white diamond's color may seem counter-intuitive at first because the most desired color in white diamonds is, in fact, no color. Color is judged by how far the diamond deviates from pure white and, generally, lower quality diamonds are those with yellowish or brownish tints. The best way to see a diamond's color is to look at it against a white surface. However, color grades are so subtle, it is often difficult to distinguish the difference with the naked eye. Gemologists grade the color of a diamond by comparing it to a master set of diamonds.

Diamond Cut

Cut is the only quality of a diamond that is controlled by the human hand, in this case, the gem cutter, who shapes the rough crystal into a sparkling gem. The gem cutter's precision is critical because it is the cut of a diamond that dictates its brilliance and fire and releases its beauty. A diamond's quality of reflection - or brilliance - is tied to how well light is reflected and refracted within the stone.
