The Onyx Black Round Pin by Adastra Jewelry is a striking blend of Art Deco elegance and modern minimalism.

Expertly handcrafted in 925 sterling silver with a platinum-finish plating, this brooch features a bold black onyx ring centerpiece, symbolizing strength and sophistication. The circular frame is meticulously set with 5A-grade cubic zirconia diamonds, forming a sparkling contrast against the deep onyx hue.

Adorned with graceful fleur-de-lis–inspired motifs, the pin embodies timeless style and refined artistry. Designed to be worn on coats, blazers, gowns, or sarees, this piece adds a statement of understated luxury to any ensemble.

Each element reflects Adastra’s signature attention to detail — a perfect union of geometry, glamour, and grace.
