Silver Dig it!

My daughter has so much fun with these. I bought several for $3. She loves all the rocks inside, but was very excited when she found real silver in one. The amount of silver is very small, but still exciting for child.

Unbelievable, they are charging $20 for this?? I bought mine at Target but it was definitely not worth it. This block only contained one tiny ugly cube of obsidian. It wasn't even the pretty red or black variations, just dull brown. Obsidian is a naturally occurring glass with no crystalline structure. Still, they cut it into a cube- which didn't improve the look and is not even educational because it's not accurate.
