I tried both the Crystal of the Month and the Crystal Variety box to see which I liked best. The Crystal of the Month comes with an awesome informative card about the crystal, which was really what set it apart for me. I love learning and so getting to learn about the crystal each month is a huge plus for me. Additionally, the Crystal Variety Box that I received came with a wonderful variety but with many small pieces. Each type would have 3 or 4 small pieces or one big piece, so i definitely feel like the value is there but personally I already have lots of small pieces so the potential for so many more each month was a negative. Either box is a great choice! That's just my rationale for going Crystal of the Month over Variety.
