MiaDonna is the world's First Lab Grown Diamond Store

We were founded in 2005 by a mother determined to free children from a lifetime of unethical diamond mining. She started working with scientists to grow the first colorless diamond in a lab, and in turn pioneered the lab-grown diamond industry. She knew the only truly conflict-free diamond was going to be lab-grown.

Superior Quality Fine Jewelry, Handcrafted in America

All our jewelry is handcrafted in the USA within 10 to 14 days. Most other jewelry companies mass produce their rings overseas in pre-stocked, limited sizes with lower gram weights. At MiaDonna, we make your ring when you order it, in the size you order, using a higher gram weight of metal, creating beautiful jewelry that is made to last a lifetime and beyond. Our jewelry makes exceptional heirlooms!

Our Diamonds And Gems Are Conflict-Free And More Affordable

We exclusively offer diamonds and gems free of humanitarian and environmental concerns because they are grown in a modern-day lab environment. Not only will you feel proud of the jewelry you wear, you will save up to 40% compared to an earth-mined diamond.

100% Recycled Solid Gold and Platinum

All of our precious metals are 100% recycled. This is extremely important because precious metals can be as conflicted as diamonds. Most competitors that offer recycled metals only use up to 60% recycled metals.

You Build Your Jewelry Just The Way You Want

Our online Ring Builder makes it so easy! Start by choosing a design from our ethical and affordable collection of engagement rings, wedding bands, wedding sets, and accessories. Then, make it your own by selecting your center stone type, shape, and carat weight (lab-grown diamonds or colored gemstones), recycled metal color, and ring size.

MiaDonna Is Woman-Founded, Women-Led, And Privately Operated

MiaDonna's founder, Anna-Mieke, is our active CEO, single mum, and lead activist for our foundation. She continues to change outdated humanitarian and environmental policies and laws surrounding mining communities.

We do not answer to shareholders, board members, large corporations, or DeBeers. We only answer to you, diamond mining communities, and the earth.

We Are this Generation's Diamond Store

When our founder, Anna-Mieke Anderson, discovered she had accidentally purchased a blood diamond, she became passionate about finding a conflict-free option. Knowing there had to be others who felt the same, she set out on a life-long mission to create the Greenest Diamond store the world had ever seen. As a result, MiaDonna & Company and The Greener Diamond Foundation were born. Since then customers like you have helped fund agricultural and education projects in West Africa, where former child soldiers are supported to grow food instead of mine for diamonds.

Lab-Grown Diamonds are here to stay. They are real diamonds, available at a fraction of the cost, without the need for destructive mining or conflict.


Highly recommend MiaDonna to anyone looking for beautiful, conflict-free diamonds and jewelry.


Trailblazers like Anna-Mieke Anderson, CEO and founder of MiaDonna, had the foresight to use lab-grown diamonds 15 years ago.
