According to the experts at the Gemological Institute of America (GIA), diamond cut is rated on a scale that ranges from “Excellent” to “Poor”, and greatly depends on the ability of the stone cutter themselves.

2. Color:

Referring to the colorlessness of a, color is graded on a scale that goes from “D: Absolutely Colorless” to “Z: Noticeably Colored”.

As Freeport’s leading diamond retailer, Frank Jewelers only sells stones of color rated M or better.

3. Clarity:

A way to record the amount of flaws (sometimes called inclusions) which occur naturally, diamonds with higher a clarity rating are usually pricier than “less clear” stones.
