I searched for the size, dimensions and quality of the stones I was looking for and then compared and ordered.

the gems were smaller than I thought but I was at fault for not reading the complete discrimination

I was looking for a small gift for a friend- the process is the same as every other time and was very simple, and she even got her gift early! On the downside, there's no way to easily keep track of multiple Shipping Addresses, so if I want to send a gift to Friend A and to Friend B, I have to overwrite everything and it's a fair bit clunky in that regard.

Found a beautiful opal at a great price. I was not disappointed when it arrived. Even better in person.

I am never let down by GemSelect. I love that you get the exact stone you want. Shipping is always in a few days. I have spread the word about GemSelect on social media jewelry creating groups that I attend. This sapphire is going to make one gorgeous ring
