Gem select was a company we were just looking at their products and my wife liked her birthstone so we ordered it and when it came she was very happy with what she received and because of that she wants to order again to make earrings with the next order so Gem Select is the company we will be shopping from now on

It was a nice and easy process throughout! The website is simple and well made I found everything I needed quickly. I needed some emeralds of a certain size for my custom engagement ring but they only had 3 available on the website, So bought the available ones and reached put to customer service to see if they have any more and they messaged me back within minutes with a list of similar sized emeralds that were not on the site! I quickly purchased my remaining emerald and they added it to my first order! I am more than pleased with the experience and I will be recommending them to anyone in the market for gems! 10/10

Excellent prices, excellent gemstones, easy to navigating, at the checkout, only a part of my cart was paid, then I get back to my chart, and the missing gemstones were there, so I pay it.At the end of the day, I did 2 consecutive purchases, paying 2 shippings. But even with that issue, I’m sure that worth it.Thanks!

I have been looking for a good place to buy gem stones for my girlfriends engagement ring and this site has stones I didn't even know existed. They have all the stones I need to bring her ring to life.

This is probably the fourth time I havebought gems at Gem Select, I have never been disappointed. I design a ring for myself, it is easier to buy the gems I want and take them to a jeweler. I am sure I will order gems again.

After working with and polishing low-grade, rough fire-agate, only to be disappointed, this shop was nirvana. The costs of some gems might seem high, but I have easily spent the same amount rough polishing lousy material only to get a few hints of fire. If you want Fire-agates, BUY the agates you want. These are excellent specimens and are worth considering.
