This Edwardian solitaire ring brings classic elegance to any collection, featuring a central old cut diamond set in a platinum claw mount. The mounting combines a platinum head with an eighteen carat yellow gold tapered band, creating a subtle contrast of silver and gold tones on the hand. One of the platinum claws shows visible wear from age, though the stone remains secure within its setting. The bright white diamond displays natural facets and captures the light across its surface. Suitable for daily wear as an engagement ring or a signature piece, the ring slips easily onto a finger for everyday styling. The narrow band tapers smoothly toward the central stone, offering a comfortable fit. Hallmarked for 18 carat gold, the piece carries the genuine character of its early twentieth century period while maintaining structural integrity for contemporary use.

Edwardian ring design, spanning roughly 1901 to 1910, is defined by the introduction of platinum in jewellery craft. Rings from this period feature delicate claw settings, refined filigree, and lightweight metalwork that highlights the central gemstone.

Craftsmen during the Edwardian era frequently combined eighteen carat yellow gold shanks with platinum settings. Platinum was preferred for securing diamonds due to its strength and resistance to oxidisation.

Authentic pieces display hallmarks indicative of the era alongside hand-cut diamonds, such as historic round cuts. Settings often feature mixed metals, with white platinum heads fused onto yellow gold bands.

A classic single stone design can be worn individually as an engagement piece or stacked alongside slim contemporary gold or platinum bands for everyday wear.

Clean the ring using warm water, mild liquid soap, and a soft-bristled brush around the stone setting. Periodic professional inspections ensure the prongs remain secure without causing wear to the setting.
