Overall Rating -> 9 star ratings

I was looking for a small gift for a friend- the process is the same as every other time and was very simple, and she even got her gift early! On the downside, there's no way to easily keep track of multiple Shipping Addresses, so if I want to send a gift to Friend A and to Friend B, I have to overwrite everything and it's a fair bit clunky in that regard.

Black Obsidian is naturally occurring volcanic glass which has been used as a gemstone since antiquity. Obsidian was named after Obsius, a Roman who discovered a similar stone. The black color in Obsidian is due to the presence of iron and magnesium.

Where is Black Obsidian found?

Black Obsidian is found in places that have experienced volcanic eruptions. Such places include Argentina, Armenia, Azerbaijan, Canada, Chile, Georgia, Greece, El Salvador, Guatemala, Iceland, Italy, Japan, Kenya, Mexico, New Zealand, Peru, Scotland, Turkey and the United States.

Black Obsidian cut, shape and treatment

Due to the opacity of most types of black Obsidian, it is usually cabochon cut, fancy cut, sphere-cut, tumbled, made into cameos or carved. Cabochon cuts also best exhibit any sheen or iridescence. Obsidian is not usually treated or enhanced in any way.

Black Obsidian Price

Black Obsidian often comes in some very large carat sizes in all manner of shapes. It is a very affordable gemstone with prices often ranging from $0.50 up to $5 per carat for all weight ranges.
