Engagement rings cost too much...... so we fixed it

We’re all about doing things differently. Creating traditions, not following them. New traditions that won’t impact you, the environment or native communities.

Founded by a consumer determined to fix the jewelry industry, MiaDonna crafts ethical, beautiful and affordable bridal jewelry using the finest lab-grown diamonds, gemstones and recycled metals. And with every product you purchase, MiaDonna will empower a diamond mining community to live a life free of poverty. So rest easy, your dream engagement ring awaits.

Our Mission

To create the highest quality and most beautiful, conflict-free engagement rings and fine jewelry available, while working to repair the land and lives damaged by the unethical conflict diamond industry.

MiaDonna CEO, Anna-Mieke

Try Before You Buy

Shopping online can be tough – we get it. But what if you could try before you buy in the comfort of your own home. Sounds nice, right?

Our Home Try-On Program let’s you do just that. Choose 3 rings and we’ll pack ‘em up and ship ‘em out. Once you’ve tried all three on, simply pack them up and ship the rings back.

It’s as easy as that!
