I was a bit disappointed honestly. I think my money would be better spent purchasing particular specimens that excite me rather than going for the surprise box. Albeit receiving a box full of mystery rocks is awesome , the contents just didn't do it for me. A large drab quartz crystal some flaky mica pieces some black looking mineral and a baggie full of points. The crystal of the month was way more satisfactory. I think I'll keep that subscription and cancel the big box. Anywho, great idea , didn't cut it for me though. Sorry!
