We founded the lab-grown diamond industry in 2005 out of activism, making MiaDonna the world's first lab grown diamond and lab grown gemstone company. We are the experts in diamonds and gems created in a lab, so you don’t have to be!

Sustainability: MiaDonna metals and lab grown diamond are certified sustainable by SCS Global and Carbon Neutral. Our company is also certified by B Corporation, so you can trust that we not only meet but exceed the highest social and environmental standards.

Diamonds: We only offer Premium lab grown diamonds. This means our lab grown diamonds are harder and brighter than other diamonds (earth mind or lab grown) on the market. You will only find this at MiaDonna.

Jewelry: MiaDonna jewelry is handcrafted just for you when you order it, unless noted otherwise. You build it online or with a MiaDonna jewelry specialist and our master jewelers will create it for you.

    Ring

    Ring us stunning. The only problem is that I ordered a sizevl 5.25. The ring would hardly slide up to my knuckles. Size is easy enough to fix. Overall I love the ring!
