Handcrafted in 18-karat gold and featuring 3 round, brilliant-cut diamonds, the Mini Catherine Key Charm has become a staple in the Jade Trau collection. The sentimental design pays homage to the vintage charms of the Victorian era, but the addition of our signature matte finish keeps this piece firmly rooted in the present. The Mini Catherine Key Charm is one of our most popular styles for hand or laser engraving.
