MiaDonna is a social enterprise and was built to give back.
DO NO HARM: The highest quality fine jewelry is made from innovative and sustainable materials that do not burden the environment or humanity.
GIVE BACK: Our conflict-free fine jewelry and engagement rings are the sustainable funding source for our foundation to empower mining communities to live a life outside of mining.
PROVE OUR WORTH: We are as tired of greenwashing as you are. All our sustainability claims are backed by third-party certifications such as B Corp and SCS Global.
Conflict-free wedding rings are ethically sourced and produced, ensuring they are free from associations with armed conflict, human rights abuses, and unethical mining practices. MiaDonna Wedding rings are crafted using ethically grown diamonds, recycled metals, or lab-grown gemstones, reducing the demand for mined resources. By choosing conflict-free wedding rings, you support fair labor practices, environmentally responsible businesses, and transparent supply chains. Conflict-free wedding rings are a meaningful choice for those who seek to celebrate love while promoting social and environmental responsibility.
A lab-grown diamond, also known as a synthetic or cultured diamond, is a real diamond created in controlled laboratory environments, replicating the natural diamond-growing process. MiaDonna’s Lab diamonds have the same chemical, physical, and optical properties as mined diamonds. Pro Tip: Not all Lab-grown diamonds are sustainable and ethical, as many diamond mining companies now grow diamonds. MiaDonna lab grown diamonds are Type 2a and “as grown,” making them harder and brighter, than mined diamonds and most lab diamonds. They are also ethically grown using slow and controlled methods from renewable energy and carbon-capturing technology.

Bold yet elegant, our two-tone wedding rings are truly a feast for the eyes! These two-tone engagement rings are made from your choice of mixed recycled precious metals for a distinct look that delivers the best of both worlds. The shimmer is perfectly accented with sparkle, thanks to the breathtaking round, oval, or pear conflict-free diamonds and gemstones that put the finishing touch on these stunning pieces.
Besides being the ethical choice, our Lab-Grown Diamonds and Gemstones are 100% real and indistinguishable from their earth-mined equivalents. They are chemically and physically identical, and even more beautiful to behold. Additionally, Lab-Grown Diamonds and Gemstones are up to 40% less expensive. The choice is clear!
By purchasing any of our two-tone engagement rings, you are powering positive change. We donate at least 10% of our profits to mining-impacted communities.

Today, we continue that mission through our non-profit foundation: The Greener Diamond. Join us in repairing lives and land devastated by gold and diamond mining.
