A Diamond's Cut Unleashes Its Light

Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond's cut as shape (round, emerald, pear), but a diamond's cut grade is really about how well a diamond's facets interact with light.

What is diamond color?

Diamond Color Actually Means Lack of Color

The diamond color evaluation of most gem-quality diamonds is based on the absence of color. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value.

More importantly, flaws impact beauty and desirability; there is much greater demand for a diamond with no flaws or very few flaws.
