Small Diamond Cobblestone Heart Charm

We’re proud to carry Single Stone’s Cobblestone Collection—where no two pieces are ever the same. Each design begins with a curated selection of vintage diamonds and gemstones in an array of shapes, sizes, and tones. The stones are thoughtfully arranged to complement the setting, resulting in a one-of-a-kind pattern that’s as individual as a fingerprint. Every piece tells its own story—uniquely timeless, uniquely yours.
