Having purchased gemstones from GemSelect before, I knew what to expect. I did find tracking information difficult to find, but beyond that, the experience was very satisfying and I will visit the website again in future.

I needed a very specific color of tourmaline and Gem Select had it. I had to get the client to agree and then ordered the stone. It arrived better than pictured and we all were very happy.
