Color
A diamond’s color grade actually measures how little color it reflects. To strike the best balance between cost and beauty, go for diamonds in the Near Colorless range: G, H, and I.

Clarity
Clarity indicates how many flaws are visible to the naked eye. Too many flaws can detract from a diamond's beauty.
Cut
Cut is the quality of a diamond’s proportions and symmetry. The better a diamond’s proportions and symmetry, the more sparkle it will produce. Cut is the most important of the 4 Cs.
Delivery Date

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.

1 Carat Round Cut Lab Grown Diamond

Cut with 58 facets — or 57, if there is no culet — the round shape was designed to produce as much sparkle as possible. As sparkle is what many people are looking for when they buy a lab grown diamond, round cuts are immensely popular. To get the most sparkle out of your 1 carat round cut lab grown diamond, choose a stone with an Ideal cut. 60% of the lab grown diamonds in our inventory are round shaped, making it easy for you to find the right one for your needs.
Not only are round cut lab grown diamonds the most sparkly, they are also the most popular lab grown diamond shape. Because of this, they are the most expensive lab grown diamond shape. Save on your 1 carat round cut lab grown diamond by purchasing a near-colorless lab grown diamond (G through J color grades). You can also save by opting for lower yet eye clean clarity grades (VS1 and VS2).
For engagement rings, round cut lab grown diamonds flatter every type of finger. 1 carat round cut lab grown diamonds are perfect for custom jewelry, such as earrings and pendants. To make your 1 carat round cut lab grown diamond appear even larger, choose a halo setting. Or let your round cut lab grown diamond stand out on its own in a solitaire setting.
