Understanding Diamond Quality

Cut, color, clarity, and carat weight each shape the character and value of a diamond.Together, they help you assess a diamond’s beauty, proportions, and overall presence when selecting diamond engagement rings or other pieces of diamond jewelry.

Cut

How the diamond works with light.
Cut affects how a diamond reflects and returns light. Precise proportions and carefully placed facets allow light to move through the stone and create brightness, fire, and scintillation. A well-cut diamond can bring a lively presence to diamond engagement rings and other fine pieces.

Color

The character of a diamond’s color.
Diamond color is graded on a scale from D to Z, with D representing the highest color grade. Diamonds closer to the colorless end of the scale allow more light to pass through with a clean, bright appearance. Color is an important consideration when choosing luxury jewelry for women or a diamond with a particular look.

Clarity

The natural details within a diamond.
Clarity refers to the internal and surface characteristics found within a diamond. These may include inclusions and blemishes formed during the stone’s natural growth. A higher clarity grade means fewer visible characteristics, making clarity an important consideration when selecting custom fine jewelry.

Carat Weight

A measure of a diamond’s size and presence.
Carat weight refers to the physical weight of a diamond. It can influence the stone’s size and presence, but carat weight alone does not determine its beauty or value. Cut, color, and clarity also play an important role when selecting diamond jewelry in the USA.
