Antique Art Deco Opal Diamond Onyx Brooch 18ct Gold With Box

Built around a magnificent natural opal cabochon, this outstanding antique Art deco opal diamond brooch is a true marvel! Weighing an astounding 42 carats (approx.), the spellbinding opal exhibits a vibrant mosaic of neon green, blue, purple, and orange flashes that shimmer and change with the light, like a fiery rainbow.

Encased in an 18ct gold gallery with intricate milgrain detailing, it is further embellished with sparkling rose-cut diamonds and black onyx around the border, with a strong pin and locking trombone clasp on the reverse to hold it secure.

Opal is the birthstone of October and is considered a stone of luck, creativity, and passion. A jewel of liquid fire, its enchanting spectrum of colours, known as “opalescence”, shimmer across the surface of the stone as if alive and evoke the natural beauty of a fractured rainbow or the Aurora Borealis dancing against the night sky.

Dating to the 1920s, this rare Art Deco opal diamond brooch exemplifies the period’s exceptional craftsmanship and elegant design, with a showstopping natural opal as its centrepiece, captivating all who behold it. It’s accompanied by its original, green velvet antique box, bearing the jeweller’s signature “Luther French” printed in gold beneath the lid.
