I can’t stop thinking about how perfect her engagement ring turned out. It’s absolutely stunning—better than I ever imagined. The way it catches the light, the way it suits her… it feels like it was made just for her. I’m honestly over the moon. Couldn’t be happier.

Great experience. it took about four weeks to get my initial ring but apparently they are built to order so that is OK. Just plan for this timeframe. The quality and build of the ring is as good as any I’ve seen. The stone is exactly as promised and came with the appropriate documentation and certification. it is beautiful. I had to get the ring resized and it was an absolutely painless process. I filled out the online form, they emailed me a return label at no cost, and they returned it after about a one week turnaround resize perfectly and absolutely no physical indications it was resized. Super happy.

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.
