Carat
Carat is the measure of a diamond's weight and size. We offer an array of high-quality diamonds ranging from 0.18 to 25.00 carats- with 1.00 carat being the most popular.
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.

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.

4 Carat Radiant Cut Lab Grown Diamond
| Radiant cut lab grown diamonds have a modified brilliant cut, making their sparkle is similar to princess cut lab grown diamonds. 4-carat radiant cut lab grown diamonds are a sophisticated choice for those who want a more extraordinary lab grown diamond shape, but still with that classic sparkle. The elongated silhouette of radiant cut lab grown diamonds will make your lab grown diamond appear larger and will make your finger appear longer and more slender. Stars who have worn radiant cut engagement rings include Jennifer Lopez and Drew Barrymore. 4 carat radiant cut lab grown diamonds are also a beautiful choice for custom jewelry, such as pendants and earrings. Radiant cut lab grown diamonds are typically rectangular in shape, but they can also be square. For a square radiant cut lab grown diamond, choose a stone with a length to width ratio of 1.05 or less. For a rectangular radiant cut lab grown diamond, choose a stone with a length to width ratio of 1.20-1.35. Choose a length to width ratio that is appealing to you - there is no correct one. Want the most sparkle in your 4 carat radiant cut lab grown diamond? Choose a “Very Good” cut grade to ensure a beautifully sparkling lab grown diamond. If you want to add additional sparkle, choose a halo setting. This can also make your 4 carat radiant cut lab grown diamond appear larger. Or let your radiant cut lab grown diamond stand out on its own with a solitaire setting. Before purchasing your 4 carat radiant cut lab grown diamond, make sure to request HD imagery of it. |
