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.

Site worked well and helped me find a rock that matched what I was looking for. Well within budget and I trust it will show up, so that's definitely positive. Not much else to it. Satisfied.
