Website is easy to navigate and the search options are great for narrowing down the choices closest to what I'm looking for. I love that all the gems are photographed individually, it helps to imagine the setting I'll have designed for each stone.

Nice images with detailed specifications, but little written descriptions. Hit or miss on what you are looking for; When you find it, you are very happy.

Its been a while since last time I bought at Gem Select. Years ago Derek Lee attended me and always was a great experience. He and his team always helped me to follow up my order and fulfilled all my needs and requests. Hope he is still around! Thank you all and keep the good work!
