Science of Sparkle

What difference can the cut of a diamond make? It’s a question that deserves a detailed answer. Each cut we make in the creation of a diamond unlocks the beauty in the form of sparkle. The final effect is magic. Over generations, we at Ritani have focused on our craft, using artistry and science to improve the brilliance, and create more of the allure that attracts us.

From Mine to Finger

Quality from
the Start

Ritani has long-standing familial partnerships with diamond mines known throughout the world for their deep caverns of the clearest, most colorless diamond rough. This ensures the ethical reputability of our diamonds, and we control the quality and quantity of Ritani diamonds available.

In order to provide the finest diamonds with the most sparkle, we begin with the nascent stone. Diamonds are rare in nature, and exceptionally clear and colorless diamond rough occurs even more infrequently. In order to create the most brilliant sparkle, our process begins with the finest diamond rough.


Taking each piece of rough by hand, our master diamond cutters use industrial lasers to analyze each diamond internally, considering all its corners and angles, to reveal the perfect diamond within. Then, our expert cutters – each with decades of experience – guide a cutting wheel to carefully cut each diamond by hand.

On principle, we will “cut no corners” to produce a larger diamond at the expense of sparkle.


With decades of experience, our Ritani gemologists are masters of the art. They have developed unparalleled craftsmanship in designing and creating beautiful rings. With an eye for masterfully designing settings and placing side-diamonds, they craft each ring with the recipient in mind. The end product is a ring that will be loved by the person wearing it, and will last a lifetime.
