Antwerp Sales International, Inc.

For over 50 years
Antwerp Sales International, Inc.
(ASI) has been in the diamond wholesale trade.

Established in 1948, as diamond cutters and  wholesalers, Norbert May created a business founded on honesty, integrity and expertise. As the business grew, so did ASI’s reputation. Known in the industry as leaders with an eye for quality, Mr. May was able to form a partnership with a European site holder. This relationship enables ASI to deliver quality goods at competitive prices.

In 1978 he was joined by his nephew, Danny Klugman. Together they expanded the business to service the 47th Street wholesale trade. This subsequently led to Antwerp Sales becoming a major diamond source for wholesalers throughout the U.S.A. market. The company’s increased clout in the marketplace translates to better pricing.

Mr. May was succeeded by Danny Klugman who became President. A.S.I. is still a service oriented family business, that specializes in GIA rounds and fancies, big parcels as well as customize picking, layouts and bagging. Antwerp Sales is now a full service diamond supplier.

Antwerp Sales manufactures and imports from .01-10.00 ct in rounds and fancy shapes ranging from D to Fancy Colors. The makes range from Excellent to Very Good. The company’s large inventory of GIA reports start at .30 ct.
