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.
As a first time GemSelect customer I can say that the website is thoughtfully designed and had pieces that I could find nowhere else. If the product delivered is as described then I will absolutely be making quite a few more purchases in the future.
First time visiting this site. I found it very well-organized which made it easy to find what I was looking for. I also like that the gem pictured was the actual gem you were buying and not a stock photo.
Very fast shipping from Thailand to Conus. Gems were as advertised. Compared to some other the other gem dealers on the web I've dealt with Gem Select are very professional. Will definitely do more business with this proprietor.
