Rose is a GIA-certified designer who spent years studying and producing professional one of one pieces while shadowing major jewelers, before creating Costolo Studio. Processing, repurposing finite materials, and the elements they are humbled to create with inspire them. Never plated, outsourced, tarnished, or discarded.

Sleek, sculptural, and unmistakably modern, the Costolo Studio 37N Ring reimagines the classic open-band silhouette with bold volume and subtle sparkle. Crafted in polished gold, the rounded ends create a fluid, organic form, with one side accented by a constellation of diamond accents for a refined touch of brilliance. Designed to make a statement while remaining effortlessly wearable, this ring balances strength and elegance in perfect harmony.
