How do I care for platinum ruby diamond jewellery?

Clean these pieces gently using warm soapy water and a soft brush to remove everyday oils from the settings. Avoid harsh ultrasonic cleaners if the piece incorporates natural gems with historical treatments. Store items separately in lined boxes to prevent the harder diamond facets from scratching softer rubies or wearing down delicate platinum prongs.

What periods do these pieces date from?

The selection spans from the late Victorian and Edwardian eras through the Art Deco and Retro periods into the mid-century. Art Deco pieces from the 1920s and 1930s make up a significant portion of the available items. Earlier Victorian and Edwardian examples often feature softer yellow gold elements combined with platinum-topped mounts, whereas mid-century designs favour streamlined geometric clusters.

How can I tell an old cut diamond from a modern one?

Old cut diamonds exhibit smaller tables, steeper crown angles and open culets visible through the back of the stone. These geometric traits result from hand-polishing techniques common before the twentieth century. Such stones produce a distinct, gentle scintillation under low light rather than the sharp brilliance characteristic of modern brilliant-cut diamonds.

Are all rubies in these pieces natural?

Many listings specify natural unheated rubies, particularly those originating from Burmese sources like Mogok. Gemmological reports often accompany these stones to confirm their origin and treatment status. Buyers should examine individual listings for specific laboratory certifications detailing whether a ruby has undergone thermal enhancement.
