This Art Deco cluster ring originates from 1930 and follows a geometric starburst design composed of platinum, diamonds, and black onyx. The setting displays a central round old-cut diamond within a bezel mounting, surrounded by a border of smaller pavé-set diamonds, millgrain detailing, and four triangular onyx inlays set against a dark background. The piece measures 1 cm high, 1 cm wide, and 1 cm deep. Today, a jewellery item of this type is worn as a decorative accessory for formal events, evening wear, or everyday personal adornment. The silver and black palette provides a stark contrast suited to a variety of contemporary wardrobes.

FAQs

Art Deco jewellery is defined by clean geometric lines, structural symmetry, abstract motifs, and high-contrast colour combinations popularised between the 1920s and 1930s.

Platinum was the primary metal of choice for its durability and white tone, frequently set with diamonds and contrasting calibre-cut gemstones such as black onyx, sapphire, or emerald.

Authentic pieces typically feature period hallmarks, hand-applied millgrain edging, complex geometric settings, and old European or transitionally cut diamonds.

A geometric cluster ring serves as a striking focal piece when worn alone alongside contemporary tailoring or paired with plain platinum band rings.

Clean gently with warm water, mild detergent, and a soft-bristled brush, ensuring non-porous stones like onyx avoid ultrasonic cleaners or harsh chemicals.
