I love the quality of the gemstones and how quickly they arrive. The service is extremely professional and high quality. I have already recommended GemSelect to a friend with great interest in Vedic Gemstones.
Great selection of gems, seems authentic (heard great things about its quality and authenticity), website's very easy to use. I would like more pictures of the individual gems from different angles but its great pictures to begin with.
If you want a gem that you can trust to not be treated, or if it is it’s disclosed this is the place! There’s something for everybody. I really like knowing that the picture of the item is the one I’m buying, not a sample or stock photo. If you make jewelry, buy gems here! You can even buy a gem and have it set by a jeweler. Again, they have an amazing inventory, and prices are more than fair. You won’t be disappointed! I just wish they sold uncut gems. Sometimes I just want a specimen in the crystal form. I’m surprised they had no quartz from Arkansas, but they have a great selection of anything I’ve ever looked for.

Diffusion treatment involves heating a gemstone with one or more chemicals. Surface diffusion affects mainly the surface of the gem, while lattice diffusion penetrates the crystal lattice. Many star sapphires are diffusion treated with rutile to improve the star. More about treatments
