Ritani Reserve
Ritani Reserve Diamonds are an exclusive selection of diamonds that have the best cut which offers maximum sparkle. They reflect the most light, maximum brilliance, fire, and scintillation.
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.
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.
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.

1.50 Carat Round Cut Diamonds

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 diamond, round cuts are immensely popular. To get the most sparkle out of your 1.50 carat round cut diamond, choose a stone with an Ideal cut. 60% of the 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 diamonds the most sparkly, they are also the most popular diamond shape. Because of this, they are the most expensive diamond shape. Save on your 1.50 carat round cut diamond by purchasing a near-colorless 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 diamonds flatter every type of finger. 1.50 carat round cut diamonds are perfect for custom jewelry, such as earrings and pendants. To make your 1.50 carat round cut diamond appear even larger, choose a halo setting. Or let your round cut diamond stand out on its own in a solitaire setting.
Before purchasing your 1.50 carat round cut diamond, make sure to request HD imagery of it. All Ritani earth-grown diamonds are certified by either the AGS or GIA – the two most respected independent grading labs in the world.
