About Obsidian
Obsidian is a naturally occurring volcanic glass. It is formed when felsic lava extruded from a volcano cools without crystal growth. Obsidian has been known since prehistoric times, and has some fascinating properties as well as some important practical uses. In addition to its use as a gemstone, obsidian has been used in cardiac surgery, as well-crafted obsidian blades have a cutting edge many times sharper than high-quality steel surgical scalpels.
In some stones, the inclusion of small, white, radially clustered crystals of cristobalite in the black glass produce a blotchy or snowflake pattern, and this is known in the gem trade as snowflake obsidian.

The Tanzanite stone is absolutely beautiful. Shipping was very fast. Very pleased with both the stone and your service.

I appreciate the how GemSelect does business, and will continue to recommend it to other jewelry makers. The photographs of the stones are excellent, making selection easy. The matched spinels from my last order were extremely good and the violet sapphire from my most recent is very nice. All were shipped astoundingly quickly. The customer service is also very prompt and professional.

You've always been great at having a nice selection. However I notice now prices have gone up on many of the items I purchawed in the past, especially the Tsavorite in 3mm, 3.5 mm & 5mm sizes Well cut gemstons. Better than expected in both color and cut.
