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.
My citrine and topaz gems ordered from gemselect were amazing. Service was fast and the details on the website were a very good match. I would recommend gemselect.com to everyone. I will for sure be back to buy more stones too.
Stone exceeded my expectations except in regards to size. Smaller than what I had anticipated. Further education needed on my part in regards to the pear shape. Maybe that had something to do with it. Plan to contact customer service regarding return/exchange for larger size. Beautiful gem and fun to watch the tracking from Thailand.
