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

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

I was looking for a site with every type of gem I could want for setting in luxury blades and assumed I would need to look outside the US, but GemSelect made it easy to get everything I wanted without leaving the house! Wide enough selection that I do not feel the need to look elsewhere and pricing the same.

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.

The site provided lots of detail, factual data, and good photos. I also like the availability of searching by price range as well as by the type of stone.
