We ordered a moissanite ring and wanted to switch to lab grown. Lab grown ring and wrap are stunning.

Both engagement and wedding ring were fantastic, my (now) wife loves them both and appreciates that they were lab grown diamonds. Best brilliance delivered both within the allotted time periods estimated, great experience.

Great company and beautiful products. I basically shopped only from the website and ordered my ring. Took almost 4 weeks but the work was excellent and quality first class. Once it came the ring was a little large and I had to send it back to get it resized. Absolutely painless process and they paid for shipping both ways by FedEx express. No issues no weird rules just good service and a great price and an amazing product. they also included a pair of pearl earrings with 14 karat gold posts I wasn’t even aware of and they are beautiful. Highly recommend!

So I had to return the first ring that I purchased due to being very dissatisfied with the quality, and even though the company refunded me and then gave me a great price on a second ring just to take down my poor review on them, I received the second ring and and once again, extremely dissatisfied with the quality. I’ll keep the ring because I’m just not gonna go through the BS with them again but suffice to say I would not buy from them as their quality just is subpar, IMO.
