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.
Excellent will be returning to make more purchases! Ordered one sapphire and one tourmaline, both arrived within 3 working days and appeared to be the exact stones shown in both pictures.Smooth transaction and very well set out website, easy to use and informative. Will definately be buying more gems from Gemselect. Gems are a little darker than they appear on the website.
I have purchased from many sites in Thailand and to date GemSelect has been the best. Prices are fair and shipping is quick. Quality is as described and website is easy to navigate. I would recommend this company to others and plan on returning in the future if prices stay competitive and service stays consistent.
GemSelect is probably the best website for buying gemstones. Their layout makes it incredibly easy to sort and filter results to find exactly the sort of stone you are looking for, which is good because their selection is enormous. I am truly impressed with their site layout and information on the product you are viewing. You get exactly what you see. I can't recommend them enough.
