1920s Diamond Trilogy Ring
A 1920s diamond trilogy ring displays three stones arranged side by side on a precious metal band, embodying the Art Deco style of the period. These rings span periods from the 19th Century through the 1920s and 1930s, often pairing diamonds with sapphires.
The most common version met on this page is the Art Deco three stone ring set in platinum and 18ct gold or 18ct white gold. Stones range from smaller accents to substantial old cut diamonds and Burmese sapphires.
Makers and jewellers of the era utilised distinct platinum settings, sometimes incorporating baguette cuts or star motifs around the central stones. Rings appear in various sizes, with options such as 9ct gold and 15ct gold also represented.
How they were made
Craftsmen during this era combined platinum with 18ct yellow or white gold to construct sturdy mountings that securely held old cut diamonds and sapphires. Platinum settings allowed for delicate claw or bezel arrangements while maintaining structural integrity.
Stones such as transitional cuts and old cut diamonds were shaped by hand, giving each ring an individual character. Gold shanks were cast and joined to platinum heads, or entire settings were forged from solid platinum.
