How do I care for antique black onyx jewellery?

Clean these pieces gently with a soft cloth and avoid harsh chemical dips or ultrasonic cleaners that can damage fragile stone settings and softer gold mounts. Store items individually in padded boxes to prevent the hardstone or surrounding diamonds from scratching adjacent pieces.

What periods do these pieces come from?

The selection encompasses Victorian and Edwardian items alongside significant Art Deco creations from the 1920s and 1930s. Mid-century and later modernist designs from the 1960s and 1970s also appear. Each era brings distinct mounting styles, ranging from sentimental mourning brooches to geometric platinum cluster rings.

How can I tell an Art Deco piece apart?

Art Deco designs rely on strict geometric symmetry, sharp lines, and strong contrasts between black onyx and white metals like platinum or white gold. These pieces often incorporate calibrated diamonds and rock crystal. Earlier Victorian or Edwardian examples tend to feature softer curves, yellow gold mounts, seed pearls, or sentimental motifs like bows and tassels.

Were these items worn daily?

Many rings, earrings and signet pieces were designed for everyday wear, utilising durable hardstone and sturdy gold bands. Others, such as large gemstone brooches or elaborate drop earrings, served primarily for evening wear and special occasions. Heavier cocktail rings and matching necklace sets reflect the bolder fashion choices of the mid-twentieth century.
