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 purchased 4 gemstones in different sizes to be able to make a family ring for my granddaughter. I got exactly what I saw and they are absolutely beautiful! Shipping was quick compared to other gem stores I have dealt with! I will definitely order more stones from your company, as I am a collector and have several stones. You are my new go to company in the future
