MiaDonna has become my go-to jeweler ever since I purchased my significant other's engagement ring through them. Their designs are varied and timeless, and their craftsmanship is second to none. The fact that they use recycled metals and lab-grown stones is just icing on the cake. My SO receives compliments about her jewelry almost daily.
The staff at MiaDonna are extremely helpful and really go above and beyond for their customers. I got my wife a 1c. diamond necklace, and her beautiful engagement ring previously, and she loved them both. Their hybrid and lab grown diamonds are incredible. It's impossible to tell the difference between these and the any diamonds you'd get from other jewelers. If you want a quality ethical diamond, MiaDonna is the perfect option.
