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 am never let down by GemSelect. I love that you get the exact stone you want. Shipping is always in a few days. I have spread the word about GemSelect on social media jewelry creating groups that I attend. This sapphire is going to make one gorgeous ring

On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc
