I love the quality, presentation and the price of the stones. I love the identification card - report they send with each stone.

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

Very fast navigation and purchase, which is good. I need to strike while the iron is hot.

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.
