I trust this company to deliver exactly what is offered. I have never had to return a selection of Gems. I appreciate the company's detailed description of their product. It helps this customer find mounts before the gems arrive. Any day of the year one can find a wide selection of gems, be it by price, color, cut, lot or single. Pricing does not jump all over the place and stays reasonable. Be assured your items will arrive in perfect condition as the company's shipping department does a great job.

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.
