Great bag of rocks that are large chunks and are smoothe and not rough.

Great sizes. Was glad to see not too small. Resealable pouch glad to get and a piece of obsidian that is cobalt blue. I presume it is obsidian.maybe something else like lapis or sodalite .thank you.

Be carful, Obsidian can be sharp, and can cut you. Still it makes a very nice, polished stone.

Tumble well

We wanted this for some practice with knapping. It works just fine. Some of the pieces are a little bit small.

Really good buy! Received a full pouch (measuring 9 1/2 inches long by 6 inches wide) of 32 pieces of real obsidian. Some pieces have a rainbow sheen on their edges. (Maybe from a prism effect. Obsidian is a natural glass. I don’t know.) The edges aren’t sharp enough to cut. I’ve found it safe to handle. The specimens are an opaque jet black, except for 3 which are more translucent. I’m going to run some through my rock tumbler and see what they become. I’m excited about this order.

I received a nice package of good quality obsidian rocks. They will be fun to use to polish or leave as is.

This is absolute garbage. This is not Obsidian, it's not natural. It's practically cement. This is an absolute scam, and should not even be allowed to be sold.
