Cushion Diamond Engagement
A cushion diamond engagement ring brings together a soft-cornered vintage gemstone cut and precious metal mount from eras spanning the Victorian period to the mid-century.
Cushion Diamond Engagement
A cushion diamond engagement ring represents a jewel designed to celebrate betrothal using stones shaped with rounded corners and curved facets. These items appear across multiple decades, reflecting shifts in taste from nineteenth-century hand-cut stones to mid-century modern designs.
The version most commonly met on this page is an Art Deco or Edwardian creation featuring an old cut or cushion cut diamond set alongside sapphires, rubies, or additional diamonds in platinum or yellow gold mountings.
Materials and construction methods
Goldsmiths utilised platinum and 18ct yellow or white gold to construct settings that secure central cushion diamonds and coloured stones. Platinum gained favour during the Edwardian and Art Deco periods for its strength, allowing intricate, delicate wirework and millegrain edges.
Stones were cut by hand rather than by automated machinery, resulting in characteristic soft facet arrangements such as old mine cuts and old cushion cuts that catch candlelight differently from modern brilliant cuts.

Diamonds cut by hand centuries ago often possess a slight asymmetry, reminding us that an artisan guided every single facet.
Distinctions in craftsmanship and stone selection
The superiority of a piece rests on the proportion and symmetry of the hand-cut cushion diamond alongside the natural origin and unheated status of accompanying sapphires or rubies. Stones possessing higher clarity grades and balanced depth command greater attention.
Metalwork integrity defines the upper tier of survivals, where claw settings, gallery piercework, and original shank thickness remain intact without excessive wear or modern replacement parts.
