Bests & Worsts Reviews from Amazon

Got this for my 10 year old son for Christmas and he thought he was the richest guy in the world after digging out his 15 gems. We almost thought we got jipped one but we didn't give up and eventually found the 15th stone which ended up being a piece of geode, that I accidentally broke so I told him it was a bonus now he has 16. The block came already broken as you can see in the first picture, not a big deal. This kit would have been even better if it included a pouch. I happened to have one handy that I gave my son to put the gems in. There were also some stones that were not listed in the Gemstone Learning Guide. I couldn't identify them any way. One that was all black (guessing it was onyx) and another that was a polished purple (maybe amethyst). I also bought him the 4M Crystal Mining kit which comes with 8 gems and was less expensive. We haven't dug into that one yet but I got one for my niece also and the gems from the 4M kit were very boring. The National Geographic ones are a lot nicer. This was a fun kit but on the pricey side.
