Shop With Confidence

MiaDonna is the premier resource for anyone looking to purchase loose diamonds. We pioneered lab-created diamonds and gemstones, but that is not all. We are also the first diamond company with a B-Corp Certification. Additionally, each and every one of our loose lab-created diamonds is GIA, IGI, or GCAL certified. 

These are 100% real diamonds — the only difference is their ethical, mine-free origin. The simple truth is that there is no reason to purchase earth-mined diamonds. Not only are Lab-Grown Diamonds significantly less expensive, but you can also feel good about buying jewelry that is free of humanitarian and environmental abuse.
