Antique Cartier Amethyst & Diamond Convertible Brooch/Pendant – 1885

$38,000.00

An extraordinary example of late 19th-century Cartier artistry, this documented 1885 creation from my grandmother’s collection is a true museum-worthy treasure. Handcrafted in the opulence of the Belle Époque era, the piece showcases a central, richly saturated emerald-cut amethyst, framed by four oval-cut amethysts of equal vibrancy. Sparkling old mine-cut diamonds accent the composition, adding brilliance to the regal purple tones.

Set in warm, buttery 18K yellow gold with platinum-topped details, this jewel is a rare convertible design, functioning as both a brooch and a pendant. The workmanship is unmistakably Cartier—precise, elegant, and imbued with the romance of a bygone age.
