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 :)

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!
