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.

I found the filter options excellent. Yours was the third site I visited (asked chat got for reputable online sellers of loose gems) and the first I purchased from as I was able to easily find what I was looking for.
