We deal in inspiration… naturally

Our mission is to buy and sell only beautiful and unique gemstones that turn us on” and, in turn, inspire the creation of fine jewelry, heirlooms that will last from generation to generation.

Beauty, Magic, Inspiration

We like to say that the Gem Trade is the second oldest profession on earth! Why did mankind bestow such value on the colored pebbles found in the sand, or in riverbeds thousands of years ago?

Travels to the mine are always part of the tradition at Mayer and Watt

With close connections to the mine, we get the opportunity to bring a wide collection of gemstones to our customers. 

With almost half a century in the industry, we have hand picked some our favorite stones. These are our rarest and most exciting gems selected to piqué a collector’s interest.

Our guarantees

When you deal with Mayer & Watt you get more than just beautiful gemstones. You gain a partner in education about gemstones, all supply chain issues regarding the environment, and Fair Trade and we promise that you will also laugh a lot!

What I love about Mayer & Watt stones is that your $10 stone is as beautifully cut and polished as your $100,000 stones!”

Simon was a very bad accountant in London, England when he stumbled into Laurie at a dinner party in Bel Air in 1979. To make a short story even shorter he married Laurie in April 1981, moved to Los Angeles, and opened Watt Gems with Laurie in November 1981.
