Our ever-growing company spans three global headquarters – Tel Aviv, Milan, and New York – each with a distinct role in the company’s extensive operations.
The journey starts in Tel Aviv, where all of our precious gemstones are acquired, sorted, cut, and manufactured. The next stop is Milan, the original home of the Sianes brothers and birthplace of SB Diamonds; as a key commercial center for design, Milan, located in the heart of Europe, remains an important strategic locationand our creative core.
Our newly remodeled central corporate headquarters are situated in the heart of New York City. The office, located in Manhattan’s famed diamond district, is a large, upscale space featuring private appraisal rooms and state-of-the-art gemology equipment. Our self-owned inventory is housed securely at all three of our locations.
As an international, start-to-finish supplier, SB Diamonds has its finger on the pulse of the industry in each pivotal region. Our constantly expanding team has unrivaled access and expertise, ensuring the best possible experience for our customers.SEARCH OUR INVENTORY
