Carat (ct) is the standard unit used to measure a gemstone’s weight. One carat equals 200 milligrams. Carat refers to weight, not size, so gemstones of the same carat weight can appear different in size depending on their cut and type.

Gemstone cuts in jewelry are all about maximizing a stone's natural beauty and brilliance. The shape and facets are carefully crafted to enhance its color, clarity, and sparkle.

A gemstone’s cut starts from raw, rough crystals that gem cutters analyze and shape, considering things like its size, shape, and how light will interact with it to create the perfect sparkle.

Diamond clarity refers to the presence of natural inclusions and surface characteristics formed during the diamond’s creation. These features are graded on a scale from Flawless to Included.

Diamonds with higher clarity contain fewer visible imperfections, allowing light to pass through more freely and enhancing brilliance, purity, and overall value.
