Not the best
Not the best quality but good enough for display.

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.

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.

This sapphire is very nice, the stone isn't very clear but it has beautiful color and is a good size, I will be buying more Jem's and creating more stunning jewelery!!

This stone looks exactly like the picture. Its color is very bright. I dont know enough about these stones to verify its authenticity but the color does not wash out.
