B CORP CERTIFIED

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.

We exist to give back. 10% of net profits fund our nonprofit foundation to reinvest positively into mining communities that have suffered too long for our love of diamonds.
