This Art Deco cluster ring originates from the 1930s and is cast in platinum. The piece holds a central marquise-cut diamond encircled by a halo of twenty calibre-cut princess sapphires in deep blue, accompanied by milgrain detail along the setting edges. Two smaller old-cut diamonds are set into the shoulders above a plain polished silver-coloured metal shank. The setting measures 1 cm high, 1 cm wide, and 1 cm deep with a finger length of 17mm, and carries a UK ring size of O1/2. The jewel is worn on the hand as a personal accessory for everyday adornment or special occasions. It suits wear as a statement cocktail ring or an alternative engagement ring, pairing easily with other fine jewellery items in a modern wardrobe. The construction shows clean metal finishes on the band alongside intricate bezel texturing around the cluster stones. The item is in excellent condition commensurate with its age and remains fully wearable for daily use.

FAQs

Originating in the 1920s and 1930s, Art Deco jewellery is characterized by geometric patterns, bold colour contrasts, and symmetrical arrangements. Jewelers frequently combined diamonds with vibrant coloured gemstones, such as sapphires, set in white metals like platinum.

Art Deco cluster rings were predominantly crafted using platinum or white gold to showcase white diamonds and vibrant gemstones. Custom-cut calibre sapphires, rubies, and emeralds were regularly fitted around central diamonds with hand-applied milgrain edge detailing.

Authentic pieces typically feature hand-cut gemstones, geometric target or marquise shapes, and fine milgrain borders. Inspecting the metal hallmarks for platinum purity and observing precision metalwork under magnification helps confirm period authenticity.

An Art Deco cluster ring functions effectively as a focal statement piece when paired with clean, minimalist contemporary tailoring. It can be worn individually on the right hand or stacked alongside unadorned platinum bands.

Clean the setting gently using warm water, mild soap, and a soft-bristled brush to remove dust and oils. Store the ring separately in a fabric-lined box to prevent harder diamonds from scratching surrounding metals and gemstones.
