Introducing the Largest Grown-in-the-United States Lab Created Diamond, by MiaDonna

Ethical Fashion gets even bigger!

Today we are excited to announce something huge! Ethical and eco-friendly jewelry company, MiaDonna, celebrates the announcement of a modern-day scientific breakthrough: The unveiling of the Largest Grown-in-the-USA Laboratory Diamond at 6.28 carats! Humanitarian Ambassador and Muhammad Ali’s daughter, Khaliah, along with MiaDonna & Company and The Greener Diamond CEO, Anna-Mieke Anderson, launched the 6.28 carat laboratory-grown diamond at the company’s Portland, Oregon showroom along with a global initiative to give back to those negatively impacted by the blood diamond industry.

Five percent of all sales fund educational, mentoring and agricultural programs in diamond-mining communities with the goal of preventing blood diamond orphan-victims from living a life of poverty.



MiaDonna offers a large variety of conflict-free diamond engagement rings and accessories that make the perfect gift for this holiday season. Their lab-grown diamonds are not only socially conscious, they are also amazingly affordable–especially in comparison to earth mined diamonds! This 6.28ct, J-Color, VS2 clarity, cushion-cut diamond costs just $52,000 while an earth-mined equivalent can cost upwards of $100,000.


In lieu of this groundbreaking news, we feel it’s only right to share some of our favorite MiaDonna lab-grown diamond engagement rings… just in time for engagement season!
