This vintage mid-century engagement ring is made of platinum and set with three diamonds, dating from circa 1950. The piece displays a large round brilliant cut central diamond held in a four-claw setting, flanked on each side by a trillion cut diamond in a matching claw mount. The polished silver-white metal band features elevated, tapering shoulders that integrate smoothly into the pierced decorated stone setting, with a legible hallmark stamped on the interior shank. The ring measures 0.7 cm high, 0.8 cm wide, and 1.4 cm deep. This classic three-stone ring is suited for wear as an engagement ring, a milestone anniversary present, or an addition to a collection of fine mid-century jewellery. The clean, silver-coloured platinum band and white diamonds provide a refined appearance that pairs easily with other fine jewellery items worn on the hand today.

During the mid-twentieth century, diamond solitaire rings featured clean geometric proportions, often incorporating platinum settings with shoulder stones such as tapered baguettes or trillion cuts to accentuate the central diamond.

Platinum is valued in jewellery making for its strength, density, and neutral white tone, which securely holds gemstones without reflecting colour into white diamonds.

Authentic pieces typically feature period hallmarks or metal purity stamps inside the shank, alongside wear patterns consistent with hand-finishing and era-appropriate gemstone cuts.

A vintage diamond ring pairs well alongside minimalist modern bands or can be stacked with complementary white gold or platinum rings for a contemporary layered look.

Clean the ring using warm water, mild detergent, and a soft brush, ensuring periodic professional checks to inspect the security of the claws and settings.
