About Your Blue Nile Diamond

Diamond Size: 0.23 Carat

The international unit of weight used for measuring diamonds and gemstones, 1 carat is equal to 200 milligrams, or 0.2 grams. A specific measurement of a diamond's weight, carat weight alone may not accurately represent a diamond's visual size. Learn More

We recommend considering carat weight along with two other influential characteristics: the overall dimensions and the cut grade of the diamond.

A cut grade is the measure of a diamond's light performance. Cut with proper proportions, light is returned out of the top of the diamond. If it is cut too shallow, light leaks out of the bottom; too deep and it escapes out of the side.

Diamond Cut

Colour: E

E colour: A "colourless" grade appreciated best set in platinum or white gold. Traces of colour difficult for even trained eye to detect.

  • For the purist, look for a colourless diamond with a grade of D-F for a diamond with no discernible colour.
  • For an excellent value in a diamond with little or no noticeable colour to the unaided eye, look for a near-colourless grade of G-I

  • Clarity refers to a diamond's relative absence of tiny, natural characteristics known as blemishes and inclusions.
  • Many of these characteristics are microscopic and do not affect a diamond's beauty in any discernible way.
