Solitaire and multi-stone rings dominate the selection, often accompanied by cluster arrangements featuring sapphires, rubies, or emeralds alongside the central diamonds. Buyers will frequently encounter five-stone half-hoop rings and delicate drop earrings designed to highlight the soft, cushion-like facets characteristic of the era.
How They Were Made
Goldsmiths shaped these mountings using eighteen-carat yellow gold, fifteen-carat gold, silver, and platinum, frequently combining silver settings on gold shanks during the Victorian era to brighten the appearance of the stones. Metalwork techniques included intricate bezel and star-burst settings, hand-carved half-hoop bands, and pierced gallery work.
Lapidaries cut the diamonds by hand under magnification, producing deep pavilions, high crowns, and small tables that captured candlelight and gaslight rather than modern electric illumination.

What Varies in Quality
Quality depends upon the symmetry of the hand-cut facets and how well the proportions of the diamond balance depth against face-up brilliance. Superior pieces maintain clean integrations between the stones and their handcrafted metal mounts without heavy past alterations.
The choice of accompanying gemstones in cluster rings and the integrity of the original claw or bezel settings further distinguish finer examples from standard production.
