IT WAS GREAT SIMPLE I WAS ABLE TO MAKE AN ACCOUNT EASY AND WAS ABLE TO FAVORITE ALL OF MY FINAL SELECTED GEMS, I JUST LOVE IT.

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've purchased from here many times over the last decade+. I find the information easy to understand, helpful, and interesting. I have always been satisfied that I got exactly what I ordered. Pictures and descriptions are clear and unique to each stone.

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.

I was looking for a site with every type of gem I could want for setting in luxury blades and assumed I would need to look outside the US, but GemSelect made it easy to get everything I wanted without leaving the house! Wide enough selection that I do not feel the need to look elsewhere and pricing the same.
