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 conserve thousands of tons of natural resources by choosing not to mine for diamonds or newly sourced gold and platinum. Instead, we take pride in growing our exceptional diamonds and maintaining a streamlined, sustainable supply chain. By offsetting the carbon emissions from production and minimal shipping with tree planting for every order, we ensure a positive environmental impact. Many of our lab-grown diamonds are also certified carbon-neutral or even carbon-negative, reflecting our commitment to eco-conscious craftsmanship.
MiaDonna is a foundation-driven company, committed to donating at least 10% of net profits from every purchase to restore lives and lands impacted by the diamond and gold mining industries. Through our nonprofit, The Greener Diamond, we actively contribute to meaningful change. As a social enterprise, we prioritize more than profit—giving back is at the core of our mission, not 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!
