An Industry Leader Since 1953

We are a third generation wholesale diamond and jewelry manufacturing company established in 1953.

We sell most shapes and sizes of diamonds. Most of our diamonds over .30 carats come with GIA reports or dossiers and are excellent cut.

We have layouts of emerald cuts, ovals, marquises and pear shaped diamonds.

We have a full service shop, including a CAD department, to custom-produce  jewelry to your specifications. Most custom designs are completed within two weeks. 

All of our diamonds are natural and never lab created.
