What is an art deco diamond trilogy ring?

These pieces feature three stones mounted horizontally across the finger, produced predominantly during the interwar decades. They combine geometric metalwork with traditional symbolism. Collectors prize them for their distinct hand-cut stones and architectural mountings that define the aesthetic of the period.

How do I wear an antique ring safely?

Daily wear requires basic care, such as removing the ring during heavy manual tasks or swimming. Platinum and gold are durable, but antique settings benefit from periodic professional checks. Store the item in a fabric-lined box away from other jewellery to prevent scratching softer gemstones like emeralds.

Are sapphires and emeralds natural in these rings?

Many listings feature untreated or minimally treated natural corundum and beryl originating from historic mines in Burma, Ceylon, or Colombia. Gemmological reports often accompany pieces with significant coloured stones. These natural gems display characteristic inclusions that confirm their origin and age.

How can I tell a nineteen twenties ring from later decades?

Early pieces often lean heavily into platinum-topped gold construction with delicate openwork galleries and sharp geometric motifs. Items from subsequent decades show heavier shanks and simpler bezel or illusion plates. Examining the shank profile and hallmark stamps helps narrow down the manufacturing decade.
