Three Guiding Principles of Sishu International

Cut :

Cut, being one of the most important element of the four “C’s” that has a very strong impact on the appearance of the diamond, we aim to ensure that some of the best cutting and polishing techniques are used to give some of the finest CVD Grown Diamonds. Not only these diamonds are indistinguishable from the natural diamonds, but they also provide exceptional value and quality.

Care :

A lot of companies that sell diamonds are either simulants or cubic zircons using marketing gimmicks, thereby making it difficult for the customers to know exactly what they are buying. At Sishu International, we are committed to provide the right knowledge along with renowned lab certificates for every product thereby empowering the customers to make informed decisions.

Conflict - Free :

We are proud to offer Conflict-free diamonds that are created in eco-friendly lab environment. The diamonds used come from legitimate sources and thus we take great pride in providing our customers with most affordable CVD-grown diamonds.

Our trade partners can always rest upon us for both consistent supply and better quality.
