Black Square Herkimer Cluster Roman Ring


Herkimer diamond quartz crystals nestle together within a square Roman bezel, capturing extraordinary depth and light. In black, the cluster feels especially striking, its layered surface revealing bright reflections as your hand moves.

The band slopes up to meet the bezel, creating a fluid, sculptural profile. Made by hand in the Pluma studio, this ring carries the character of ancient metalwork in proportions that are easy to wear every day.

I gave a Universe necklace to my mom to represent all her grandchildren. She cried and even my dad got emotional. She loves it so much.

Pluma is an outfit maker and I love that I can change it up with layering it together.
