Choosing the most high-quality diamonds requires a trained eye to analyze four key elements. At Diamond Castle Jewelers in Novi, Michigan, our jewelers can help you find the brilliance and magic you’re looking for. It’s what we’ve done since 1902, and what we continue to do for you.


Refers to the symmetry, and reflective qualities of a diamond, the cut is directly related to its overall sparkle.


The clarity in the diamond comes from the type of cut and how prestigious the diamond is. To obtain a higher clarity grade, a diamond would have to maintain fewer inclusions and blemishes.

Carat Weight

Carat is the unit of measurement used to describe the weight of a diamond, not the size, but it is often the most visually apparent factor when comparing diamonds.


Color refers to the natural color or lack of color visible within a diamond. There is a range from “colorless” and “near-colorless” with the closer a diamond is to “colorless,” the rarer it is in value.
