This hand-carved Cosima ring celebrates the romantic charm of antique diamonds with modern sensibility. The .43ct Old European cut center stone brings that coveted vintage sparkle, softer and more romantic than today's precision cuts. Sparkling Canadian diamonds (.12ct total weight) are flanking the antique beauty, creating a brilliant constellation along the band.

Each stone is carefully bezel-set for everyday durability, while the thoughtful hidden shelf design allows your future wedding band to stack flush against it. It's old-world romance meets contemporary craftsmanship, perfect for someone who appreciates the story that antique stones whisper through their facets.

OLD MINE & OLD EUROPEAN CUT DIAMONDS

Precursors to today’s modern round brilliant, these antique treasures come with undeniable charm. Most of them are from the 1700s and 1800s — used in jewelry designs from the Georgian, Victorian, Edwardian, and Art Deco eras. They have wide, geometric facets that offer bright pops of sparkle and are designed to be their most dazzling in low light.
