Finding the right diamond

The measure of a diamond’s beauty is a well-executed cut. Using the 4Cs can help you find the perfect diamond. Carat: Carat is the unit of measurement for a diamond's weight. Rarity means larger diamonds of the same quality are worth more per carat. Clarity: Clarity refers to the purity of the diamond and assesses the number, size, relief, and position of inclusions and blemishes. Color: Color refers to the color within the diamond, not the reflected light. The less color there is, the higher the grade. Even the slightest hint can make a dramatic difference in value. Cut: Cut refers to a diamond's symmetry, proportions, and polish, which determine how the diamond’s facets interact with light. Shane Co.'s diamond buyers go to the stone cutters around the world and hand-pick diamonds with the most sparkle from within each grade for our stores and our website. Whatever diamond grade you choose, you will clearly see the difference in the way Shane Co. diamonds sparkle.

Can you buy loose diamonds?

Buying a loose diamond can offer many benefits. When you purchase a center diamond stone separately, you will be able to find a diamond that matches your desired specifications and quality characteristics. Once you find the perfect diamond, you can have it mounted on your chosen setting for a beautifully customized piece.
