About Snowflake 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.
I've been very satisfied with the gems I have purchased since 4 years ago. Good service, variety, clear information regarding the stones for sale and very interesting gemstone information. Congratulations!
I really like the selection from GemSelect. My only complaint is that I would occasionally want a singular small gem for a small setting, but would only be able to find appropriately sized gems sold in pairs or more. There is a limit to how small of a gem that can be bought independently that I dislike.
Strengths: I LOVE the huge range of gems you offer, including collector's gems that are hard to find anywhere else. I also love the range of information provided, and the monthly newsletters!
Weaknesses: Due to the great range of inventory (a strength!), it's hard, even with all the useful filters, to narrow the search parameters enough! Suggestions: Add even more filters, such as "emerald green," not just "green," to your color filter choices. (Yes, just what you wanted, more coding work!)
Overall: Your site is incredibly valuable to gemhounds everywhere, whether we be jewelers, geologists, or just interested browsers. A wonderful resource!
