A round solitaire engagement ring centres a single central stone in a timeless profile.

Round Solitaire Engagement Ring
A round solitaire engagement ring showcases a single principal diamond or gemstone mounted upon a precious metal band. The selection spans periods from the late Victorian era through Art Deco, Edwardian, and mid-century designs.
The version most frequently met on this page pairs a substantial centre diamond with a durable platinum setting or an 18ct gold band. These configurations reflect the prevailing styles of the 1920s, 1930s, and 1950s.
Makers utilised various precious metals, combining platinum with yellow gold or white gold to secure the central stone. The resulting jewellery ranges from minimalist bands to pieces featuring delicate shoulder diamonds.
How they were made
Goldsmiths worked primarily in platinum and 18ct gold, casting and forging metal to construct secure settings for centre stones. Platinum became the preferred choice during the Art Deco period for its strength and bright finish.
Cut techniques evolved across the decades represented, moving from old European and old mine cuts to transitional cuts and modern brilliant cuts. Stone cutters shaped facets by hand in earlier examples to maximise brilliance under candlelight.
Materials documented in these rings include platinum, 18ct gold, 18ct white gold, 18ct yellow gold, and 9ct yellow gold.
What varies in quality
The weight, clarity, and colour of the centre diamond heavily influence the overall character of a round solitaire engagement ring. Larger carat weights combined with minimal inclusions command attention.
The precision of the metalwork and the integrity of the prongs holding the stone define the standard of craftsmanship. Heavier platinum mountings and well-balanced proportions separate exceptional examples from standard production.
