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.

Very nice stone complete with card with certification number on it.
I picked this stone to make a sapphire ring for my grown son. I was nervous before it arrived hoping it would be the right size and shape to tumble for a wire wrap ring and when it arrived I was pleasantly surprised. I will say that right now it's in Grit 3 (prepolish). I only kept in in Grit 1 for three days because by that time, it had smoothed out perfectly. I also shortened Grit 2 and am shortening Grit 3 as well. I likely keep the polishing grit at full recommendation. However, I wanted to note it that the coarse grit tumble may take more stone off than you want if you're not careful. As it is, my stone is the perfect shape, the color is magnificent and I couldn't be more pleased. I would definitely buy from this vendor again to see if I get the same quality another time.

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.

Beautiful stone, but weight was off
It looked much like the picture. Very beautiful color. The size was not as Stated. It weight almost 8 not 9 carats. The stone quality was good. Value was okay.

Natural Blue Sapphire
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.
