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.
I purchased a yellow sapphire for about $145 with shipping and the Gem Certificate. I used the $10 shipping option and it arrived 2 days early. (Please note that if you want a Gem Certificate, it can take up to 5 days longer to be delivered) The gemstone looked exactly like the picture and video. I am so excited about the quality and price! Please note that the Gem Certificate does not say the clarity for some reason... 150% happy with this website, and would use it again!
Have placed several orders this year, but this was the largest gem order. I had several unusual requests to make and the customer service handled each beyond my expectations. CUSTOMER SERVICE COULD NOT BE BETTER. As said before ...
