I love it.

Sapphire is my birthstone. But this raw crystal speaks to me. I have much to learn with it; I’m looking forward to making a pendant with it.

Dyed stones

Seller should be more clear that the stone is dyed. Purple dye all over my hands. Very disappointing. Stone is very small. Not as represented at all. Not a reliable seller.
