How these rings were made
Master metalsmiths utilised dense, strong platinum to create intricate milgrain edges and fine wirework that could hold stones securely with minimal visible metal.
Gems such as old European cut diamonds, unheated sapphires and emeralds were shaped by hand, resulting in softer facets and characteristic deep culets unlike modern brilliant cuts.

Antique Platinum Engagement Ring: Frequently Asked Questions
What periods do these rings come from?
These rings span several decades from the late Victorian and Edwardian eras through the Art Deco period and into the mid-century years. Each era brings distinct design characteristics, from delicate floral motifs to stark geometric configurations.
Platinum gained widespread favour in jewellery manufacturing during the early twentieth century due to its remarkable durability and bright white finish. This material choice allowed artisans to build lighter, stronger settings that maximised the brilliance of the mounted diamonds and coloured gemstones.
How do I care for an antique ring?
Daily care involves removing the ring during rigorous physical activities to protect the delicate platinum prongs and hand-cut stones from impact. Gentle cleaning with warm soapy water and a soft brush helps maintain the brilliance of old-cut diamonds.
Periodic inspection by a specialist jeweller ensures the security of historic settings and milgrain edges. Avoiding harsh chemical cleaners preserves both the gemstones and the original metal patina built up over generations.
What is an old cut diamond?
An old cut diamond is a historic gemstone shaped entirely by hand before the invention of modern automated sawing and laser techniques. These stones feature smaller tables and deeper pavilions that produce a softer, candlelit sparkle.
Each old cut diamond is unique because the proportions were adjusted by the cutter to retain maximum weight and beauty from the rough crystal. This hand-shaped individuality distinguishes antique rings from contemporary manufactured jewellery.
Are coloured gemstones treated?
Many historic sapphires, rubies and emeralds found in these rings originate from classic sources like Burma, Kashmir, or Colombia and exist in entirely natural, unheated states. Documentation often notes the absence of artificial treatments.
Evaluating coloured stones requires looking for natural inclusions that confirm their geographical origin and geological history. These unique internal characteristics offer proof of authenticity for collectors seeking untouched historic gems.
