Diamonds are nature’s time capsules. They formed billions of years ago deep in the earth’s mantle and were carried to the surface by volcanic eruptions. Chances are you’re familiar with the four Cs.

CARAT

A carat is a standard unit to measure the weight of a diamond. One carat is equivalent to 200 milligrams. A higher carat weight does not necessarily mean a more valuable diamond. A smaller diamond can be much more expensive than a bigger diamond with lower clarity, color or cut.

CUT

Attrē is about the love for fancy cut diamonds, which describe all shapes besides rounds. The cut refers to the diamond's proportions, symmetry, and polish. It impacts the diamond’s brilliance and fire. Well-cut diamonds reflect light better, resulting in maximized sparkle. The quality of a diamond cut is categorized into five grades: Excellent, Very Good, Good, Fair, and Poor.

CLARITY

Diamond clarity refers to the presence of natural inclusions and is graded on a scale from Flawless (FL) to Included (I). The highest clarity grade diamonds are extremely rare and priced according to their quality.

COLOR

White diamonds are also graded, referring to the natural presence of hues of color. The scale goes from D (colorless) to Z (light yellow).
