Richard Krementz Gemstones

This United States Jewelry manufacturer

began in 1866.  They were based in Newark NJ. At one time they were the largest jewelry manufacturer in the world.

The name has always been synonymous with quality, especially colored gems.

Krementz color was the buzzword in Tucson at the American Gem Trade Show. Sadly in February 2013, at the AGTA show the company closed following the death of it's leader Richard Krementz, Jr.

​I was lucky enough to purchase many pieces of their remaining stock. So I am now able to offer them at less than original wholesale cost. History combined with quality, a formula ​for value.
