Polish
A well-polished diamond will have excellent light return.
Fluorescence
Some diamonds glow blue or green when exposed to UV light. Since fluorescence is rarely visible, it has minimal impact on the appearance of your diamond. To save money, go for medium fluorescence.
Depth
Depth percentage correlates with a diamond's sparkle factor. It is measured by dividing the diamond height by its diameter. For maximum sparkle, the depth percentage of a round diamond should be between 54% and 66%.
Length/Width Ratio
The proportional relationship between your diamond’s length and width. A perfect round diamond would measure equally 1-to-1, so its LxW ratio would measure as 1.
Symmetry
Symmetry tells you how well a diamond’s facets align to create sparkle. Diamonds with perfect symmetry create the most sparkle and earn a grade of Excellent or Ideal.

Table
Table percentage tells you how big a diamond’s topmost facet (aka table) is in comparison to its diameter (aka girdle). When that ratio is in the right range, a diamond will sparkle more.
Culet
The culet is the point at the bottom of the diamond. If the point has a facet on it, it can stop light from reflecting and detract from the diamond's sparkle. Choose a diamond with no culet for optimum sparkle.
Certificate
All of Ritani’s natural diamonds are certified by either the GIA or AGSL, the industry’s two most respected grading labs.
