Our Inventory

The foundations of a reputable diamond business began in 1963, when Shlomo Kuperman established his small manufacturing operation in Netanya, Israel. An ambitious young man, he employed the precision and the perfection demanded to excel as a diamond craftsman. With the success of his handiwork, the business grew and Shlomo brought his family members into the business, including his brother,Udi, with whom he shares the business name. Many employees who have joined the business remain for many years — even decades — as an integral and loyal part of the team.This factor has contributed significantly to the longevity of Kuperman Bros. and its enduring quality in production and service.
