  • Description & Details

  • Every radiant cut diamond ring is designed and crafted by Plum to your exact specifications. Plum's ethically-sourced diamonds are 100% lab created and curated for quality. Our ring settings are made with the best materials available — including recycled metals whenever possible — and undergo stringent QA in our own certified-responsible manufacturing facility. We don't purchase or use inferior mass-produced mountings that can easily bend or break.

    Measurements and carat weights are approximate. We craft rings to strict tolerances. However, keep in mind that all Plum rings are set, polished, and finished individually by hand, so slight variations are normal.
