Antique Victorian 17k Yellow Gold .77ctw Old Mine Cut Diamond and Onyx Brooch

A striking navette-shaped onyx centerpiece gives this antique Victorian brooch a dramatic and refined presence. Set in 17k yellow gold, the elongated silhouette is centered by a vertical arrangement of old mine cut diamonds totaling .77ctw, their soft antique sparkle contrasting beautifully against the deep black onyx. The brooch features a balanced Victorian composition, with tapered gold ends, delicate bead accents, and graceful wirework details that add movement and period character. The warm gold setting enhances the richness of the black onyx while framing the diamonds with a romantic, heirloom-quality feel. Elegant and distinctive, this old mine cut diamond and onyx brooch captures the sophistication of antique mourning-era inspired jewelry while remaining beautifully wearable. It is a refined accent for a lapel, collar, scarf, or collected antique jewelry display.
