Offering Expertly Cut and Polished Diamonds in Kolkata

Kolkata has become a significant market for polished diamonds. Polishing the diamond transforms the rugged stone into a gleaming jewel. Because diamonds are the hardest natural material. This is why diamonds can only be polished by other diamonds. Experts use diamond dust and lubricant (often olive oil) to create a “diamond paste”. This helps to polish the diamond. The process produces smooth and precise facets. These aspects bounce light, bringing brilliance and fire. We offer polished diamonds with “Excellent” or “Ideal” polish grades.
