GemSelect is always my first choice for purchasing gemstones. The fact that the gems are always exactly as described and pictured on the website has earned my trust many times over. Even when I don't buy, I still love browsing all the beautiful stones. My new favorites are the bright green Tsavorites!

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.

I did not realize these stones were of jewelry quality. They are really beautiful, just not what I was expecting which was more of a natural stone.
