Natural black obsidian beads.

Obsidian is a glass-like volcanic stone resulting from the rapid cooling of lava. Being an amorphous stone, it does not have a geometric crystal structure like other minerals. Obsidian is most commonly black but can also be gray, dark brown, green, and everything in between.

Black's always a good choice

Versatility is what these stones have. Lots of combinations and fun!

The search is over!!

I have always admired terahertz for its sparkle, lightness and complimentary addition to my designs. When I discovered Tejas Beads, I was thrilled to find terahertz in multiple sizes AND at a fantastic price. I started doing designs which featured the bead and had immediate interest from others.

My first design turned into a Christmas gift when I showed the photograph to a friend. Since then, I have made multiple bracelets and necklaces for multiple people. The simplicity of the design and the sparkle of the bead has turned it into the perfect present!

Since discovering Tejas Beads, I've been able to add even more options for my designs. I'm now looking forward to expanding my designs in 2026.
