Great selection, the user interface was somewhat irksome. If there was a way to filter out specific items (I.e. particular treatments to the gemstones), or would greatly improve the site. Otherwise, great!

Very good value for the money. Great pictures that can be enlarged. Length and Width and carat size, and several angles that the gems can be viewed. Some of the gems have videos!

I think the GemSelect website is exceptional. It gives me comfort and confidence that what I select is what I will receive from them. This is why I buy from them. I've purchased many gems from them online and have never been dissatisfied. I like the paperwork that ships with the orders and the reports that are available.

It's got all the gems you could want but definitely use the desktop site the mobile one is difficult to navigate.

I have purchased several times from GemSelect and am always pleased with the stones. The information on the site about each stone is thorough. I don't have to worry about fake stones from them and the prices are quite reasonable. I love the new cards provided for each stone. I would highly recommend them.
