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

I love the variety of stones available, and especially that I'm not buying from a stock image -- the stone I see online is the actual one I'm getting.

I've been collecting gemstones for a while now so I wad excited that I found a relatively cheap site to gems from. When I opened to package i was a little surprised and how small they were but it's literally marketed for jeweler's so I understand why my little square cut sapphire is the size of a crumb, but all in a ll I'm very happy with what I ordered.

This site is *amazing*! The vast selection is almost enough to make you giggle. Oh, wait…If you want it, it’s probably here. I’ve read some reviews saying it’s hard to use the search filters but I found the opposite to be true. In fact, it’s plain fun to throw different filters on and see what you come up with. I ordered a small stone to sort of try them out and, dang! I’m so thoroughly impressed that I think I found a new hobby. The stone I got was exact what was represented on the site. So much so that I had to really look to see the difference between the picture and the stone that I got. And the range of prices. Wow! From a few dollars to tens of thousands if you’re into like, Ruby’s, Emerald’s, Sapphire’s and other gems that make you drool. And the cuts! The shapes and cuts are just plain gorgeous!Honestly, I can’t possibly say just how happy I am with this purchase! Now… off to make another…

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size
