Gemstones

Exceptional Stones. Personally Sourced.

At Tull’s Gem Co., we believe the right piece of jewelry begins with the right stone.

We personally source distinctive gemstones with a focus on Thailand’s world-renowned gem markets, while also working with trusted sources around the world. Our goal is simple: find gemstones with exceptional beauty, character, quality, and value.

Each gemstone is considered individually for its beauty, character, quality, and value.
