I highly recommend D.NEA diamonds (email to get their full inventory, a lot is unlisted) which has a upgrade policy of any stone greater than the original purchase. This is the best upgrade policy I’ve seen on lab diamonds, and it was a pleasure to work with Eric. I’ve also been told D.NEA is where BrilliantEarth sources some of their stones.


Soha Diamonds is also another great choice, Aubree and Soha really know their stuff and will even video call you to compare two of any of the stones they source for you. They also do custom designs, and they used to have an upgrade policy… but I can’t find it on their website anymore.


I also purchased from BrilliantEarth, but ended up returning the stone as I was having doubts and Eric offered to send me a D.NEA stone that was ~$3000 LESS with better specs. I found identical stones (same IGI #) on BE, Soha, and D.NEA, and both Soha and D.NEA were always marginally cheaper than BE. The fact that they have no upgrade policy, and the recent shady lawsuits on their “ethically” sourced stones turned me away from them eventually. 


I never found any good quality diamonds on CleanOrigin, (specifically around the right dimensions for optimal light return) which is what I think makes their price so low, but it may have just been for the carat range I was looking for. 


Sorry for the novel, just wanted to share after everything I found! Best of luck!

Although I know you’re looking online, I just thought I’d throw it out there that most jewelery stores can source a lab stone for you.  That’s what my fiance did for my ring and my stone is beautiful.

Yasamine co has lab diamonds and I found their prices are even more reasonable than CO. They will also custom cut a stone for you if you want something specific that isn’t in stock.
