Miansai’s Valor Spinels Signet Ring updates a centuries-old silhouette with a sharp, industrial edge. Forged from solid sterling silver, this ring features a recessed square face meticulously set with black spinels—stones prized for their deep, obsidian-like luster and exceptional hardness. The result is a low-profile statement piece that balances the weight of a traditional signet with the refined detail of high-quality pavé stonework.
