MiaDonna's fine jewelry is handcrafted using 100% recycled solid gold and platinum at a higher gram weight, meaning your jewelry will last for generations. Our Lab-Grown Diamonds and Gemstones are among the Top 1% of all diamonds and gems, no matter their origin.
We save thousands of tons in natural resources by not mining for diamonds and new gold or platinum for our jewelry. We proudly grow own our exceptional diamonds, and boast a short supply chain. Carbon emissions required for production and minimal shipping are offset by planting a tree for every order. Many of our Lab-Grown Diamonds are certified to be carbon neutral or carbon negative.
MiaDonna is a foundation-first company that gives at least 10% net profits from every single purchase to rebuild and repair the lives and land devastated by the diamond and gold mining industries. We do this through our foundation, The Greener Diamond. As a social enterprise, we measure more than profit. Giving back is crucial part of our business, and never an afterthought.
We hate greenwashing and deceptive marketing as much as you do. We're proud of our many third-party certifications that prove our bold, industry-leading claims. As the first B Corp-certified diamond retailer, we continue to meet the highest standards of social and environmental impact. We use business as a force for good.
I’ll never order from anyone other than Miadonna. The ease, kindness, and support of the ordering process pre and post, and the quality of the jewelry is stunning. Ordered this for a home try on and even the quality of those pieces is next level.
I wanted an oval diamond with a thin gold band and the hidden halo is such a perfect touch! This is a 1.5 carat. Couldn’t be happier and super happy to give our business to a sustainable company! Will be shopping Miadonna for a matching wedding band :)
Thank you, Kenzie for your wonderful review. The Millie is definitely a favorite with the team here at MiaDonna. Thank you so much for choosing MiaDonna and enjoy wearing your gorgeous ring. We look forward to helping you choose a wedding band when the time comes.
I was looking for an engagement ring with ethically sourced diamonds and I was extremely fortunate to find Mia Donna. The Millie Hidden Halo caught my eye while browsing the site. It is sleek, simple, elegant, and fairly priced. I ended up going with the Millie with an oval cut stone, and my fiancé absolutely fell in love with it (she said yes!). The halo is an understated and gorgeous detail that really adds a lot of character to the piece. The band is on the thin side which really makes the diamond pop and is perfect for pairing with a wedding band. Awesome!
