Review: 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.
Review: 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.

## Features

- Color zoning is responsible for certain Sapphires having lighter and darker colors in different parts of a crystal. Some Sapphire gemstones may even be multicolored such as purple and blue. Sapphire is a tough and durable gem, and the only natural gemstone harder than Sapphire is Diamond. Despite this, Sapphire is still subject to chipping and fracture if handled roughly, and care should be taken to ensure it is properly handled.
- Display a lighter and more intense color when viewed at different angles. Some pleochroic Sapphire is blue when viewed at one angle, and purple at a different angle. Color zoning, which forms from growth layers that build up during the formation of the stone, may also be present in certain Sapphires.
- Our Expert gemologists verified this Blue Sapphire which passed many quality base tests and get stone certified through which we are completely assured of Top Quality Gemstone. Only after that, we deliver stones to you because we also, care about your loved ones.
- Perfect For: Jewelers, Jewelry makers, Goldsmiths, Designers, Craftsmen, Collectors or a gift for the special one. Each and every stone is unique and you will receive ones similar to the image shown.

### ⭐ Dyed stones
*by C***7 on July 14, 2025*

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.
