Art Deco 18ct Yellow Gold & Platinum Diamond Bypass Ring, Size L ~0.26ct

A delicate and finely crafted Art Deco two-stone diamond ring, dating to the 1920s –1930s. Made in 18ct yellow gold with a platinum-topped setting, this ring beautifully exemplifies the geometry and balance typical of the era.

At the heart of the design are two old-cut natural diamonds, together weighing an estimated 0.21 carats. These are set side-by-side in a platinum box-style illusion mount, creating the iconic “toi et moi” silhouette symbolising love and unity. The shoulders are finished with six smaller old-cut diamonds, delicately bead-set in platinum with fine milgrain edging. These accents elevate the visual impact while retaining a refined, minimal elegance. 

This is a superb example of British Art Deco jewellery, suitable as a unique engagement ring, anniversary gift, or treasured addition to a fine vintage collection.
