Half Carat Diamond
A half carat diamond sits at the heart of these rings, appearing in solitaire, multi-stone, and cluster formations alongside sapphires, rubies, and opals. Buyers searching for a half carat diamond encounter designs spanning the Victorian, Edwardian, Art Deco, and Mid-Century periods.
Solitaire engagement rings and five stone bands dominate the selections, alongside half eternity and cluster rings. Yellow gold, white gold, and platinum mountings frame the stones, reflecting the shifts in metal choice from the late nineteenth century through to the mid-twentieth century.
How they were made
Goldsmiths worked primarily in eighteen carat yellow and white gold, alongside platinum, shaping bands to hold old cut, brilliant cut, and transitional cut diamonds. Stones were secured using claws, bezels, and channel settings designed to highlight the individual brilliance of each gem.
Makers integrated coloured gems such as sapphires, rubies, and turquoise alongside the diamonds in multi-stone configurations. Hallmarks stamped into the metal indicate assay offices and periods, recording the origin of each piece.

What varies in quality
The distinction between pieces rests in the relationship between the diamond cut, the setting work, and the preservation of the metal mount. Hand-finished settings and symmetrical stone arrangements demonstrate greater attention to detail by the original maker.
The choice of cut, whether an older hand-faceted old cut or a later brilliant cut, influences how light moves through the stone. The integrity of the gold or platinum band and the security of the stones within their mounts shape the overall character of each ring.
