Diamond Size: 0.3 Carat
We recommend considering carat weight along with two other influential characteristics: the overall dimensions and the cut grade of the diamond.Learn More
Good cut: Quality at a lower price than a very good cut, still producing a beautiful diamond for the budget-minded.

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.
H color: A "near-colorless" grade, color is only noticeable when compared to much higher color grades. Excellent value.

- For the purist, look for a colorless diamond with a grade of D-F for a diamond with no discernible color.
- For an excellent value in a diamond with little or no noticeable color to the unaided eye, look for a near-colorless grade of G-I
SI1-SI2: Slightly included. Inclusions noticeable at 10x. Best value if eye-clean. SI2 inclusions may be detectable to a keen unaided eye.
Want to learn even more about clarity? Learn More
- 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.
