Classic and Contemporary Designs

The single-diamond ring is an enduring style that exudes luxury while retaining its graceful demeanor. Our master designers have created a wide variety of solitaire engagement rings so anyone can find their personal version of utter perfection. From dainty and delicate to ornate and opulent, we go above and beyond to provide an eclectic selection of the finest pieces to symbolize love, commitment, and partnership.

Whether you prefer beautiful minimalism or unabashed extravagance, we have a solitaire wedding ring for you. Best of all, they are made ethically and sustainably to align with your values and ours. Lab-Grown Diamonds and Gemstones are every bit as real as their earth-mined counterparts — they are physically, chemically, and optically identical. They are simply more beautiful, more affordable, and most importantly, conflict-free.

Jewelry That Powers Positive Change

These solitaire engagement rings come with a purpose beyond commemorating your engagement. MiaDonna donates at least 10% of our profits to The Greener Diamond — our non-profit foundation that actively supports communities negatively affected by the gold and diamond mining industry. Your purchase will make a major difference in repairing lives and land devastated by cruel business practices.

If you have questions or want to modify any of our single-diamond ring designs, please contact us. Our non-commissioned jewelry experts would be delighted to assist you with your acquisition. We also welcome you to create your very own unique ring design if you have a specific vision in mind. All solitaire engagement rings include free USA shipping, free 30-day returns, and free resizing (one full size up or down within the first 90 days of purchase). Explore our breathtaking conflict-free engagement rings now, and power positive change with your purchase.
