Decades of antique collecting have led us to offer this rare opportunity: a meticulously recreated Edwardian solitaire ring, cast from molds made using original antique mountings. Designed to hold a three-carat antique cushion or any 9mm stone, this setting blends contemporary craftsmanship with timeless period authenticity, including milgrain, filigree, and delicate period details—expertly faithful to early 1900s originals.

Offered as a mounting only, including six old, earth-mined side diamonds—ready for your own unique center stone. Made to order.

Helping you find the perfect fit is our priority. There is a flat fee of $60 to size down. The sizing-up cost varies based on width of the ring and the amount of material required.
Keep in mind that finger sizes fluctuate due to factors like temperature and time of day. Rings with an open space under the mounting, as well as contour bands, may fit differently than fully round rings.
