Platinum Cushion Cut Ring
A platinum cushion cut ring combines crisp, durable metal with the soft, rounded corners of an antique stone for daily wear.
Platinum Cushion Cut Ring
A platinum cushion cut ring displays stones shaped with gently rounded corners and larger facets that catch candlelight differently than modern brilliants. These rings span from the late nineteenth century through the mid-century decades, covering Victorian, Edwardian, Art Deco, and Mid-Century styles. The platinum settings often incorporate intricate piercing and millegrain detailing that frames the central gem.
Diamonds dominate the selections here, frequently cut as old mine or old cut stones with characteristic high crowns and small tables. Alongside diamonds, pieces feature sapphires, chrysoberyl, aquamarine, amethyst, and pink spinel set into bright white platinum or combinations with yellow gold. The forms range from simple solitaires to trilogy rings and substantial multi-stone cocktail designs.
Engagement rings make up the bulk of these listings, reflecting the enduring appeal of durable platinum for lifelong wear. The pieces hail from periods spanning the 1870s to the 1960s, with a strong concentration of Art Deco and vintage mid-century examples. Each jewel carries the unmistakable hand-finished character of its specific decade of origin.
Materials and Construction
Platinum serves as the primary structural metal for these rings due to its strength and bright white lustre, which allows for delicate claw settings and secure bezels without bulk. Goldsmiths of the early and mid-twentieth century worked this dense metal by hand, piercing galleries and rolling fine millegrain borders along the edges of the settings.
The central cushion cut stones, whether diamonds or coloured gems like unheated sapphires and chrysoberyl, were shaped by hand before standard machine cutting protocols took over. This manual faceting creates the distinctive soft brilliance and deep culets seen in old mine and old cushion cuts.
Accent stones such as smaller diamonds, onyx, or calibrated sapphires are flush-set or channel-set to complement the central gem without distraction. The marriage of platinum with underlying gold or mixed metal components appears in select pieces from the Art Deco period, demonstrating skilled multi-metal assembly.

Factors That Separate Examples
The quality of a platinum cushion cut ring rests heavily on the original hand-cut proportions of the central stone and how sympathetically the platinum mount holds it. Master lapidaries shaped these cushion stones to maximise light return within the constraints of rough crystal, meaning symmetry varies from piece to piece.
The crispness of the hand-carved pierced work and the uniformity of the millegrain beading distinguish finer workshop output from simpler production. Minimal wear to the delicate platinum claws and prongs indicates careful past maintenance and preserves the structural integrity of the setting.
The provenance of the centre stone, such as unheated origin for sapphires or certified diamond grades, elevates certain examples above standard decorative pieces. The harmony between the geometric rigour of Art Deco mounts and the organic softness of the cushion cut dictates overall aesthetic success.

Can these rings be resized safely?
Most platinum rings can be altered by a skilled jeweller who works regularly with antique metals, though intricate side engraving may require careful restoration afterwards.
