About us

Rough And Cut Gemstones. Diamonds and
Colored Stones. I am an old timer gem dealer gemologist. After I left graduate school in physics I started gem business around 1970. Most of my items are old stock imported many years ago at old prices. I am not merely one who buys wholesale and sells retail but one who invested in gems for more than 40 years and am selling mostly old stock not available on today's market. Also I sell some new items which are still available to me. Only one diamond left in my store. The rest were sold. These were imported many years ago and mostly sold now.
