A unique, highly detailed, and extremely pretty diamond ring. The centre stone - weighing a known 0.73 carat - is secured within a hexagonally shaped setting, and is flanked on either side by two elongated trillion cut synthetic sapphires (synthetic accent stones were common in this era).

Why Sellingantiques dated this piece to THE 1960s:
Old European cut diamond: an earlier hand-faceted stone reset into this mount.
Pierced geometric gallery: Art Deco revival styling from the mid-twentieth century.
Triangular synthetic sapphires: lab-grown calibre accents common in twentieth-century jewellery.
Rubbed engraving on the lower shank: surface wear from long handling.

This 1960 ring follows an Art Deco Revival style in silver and blue tones, fashioned from 18k white gold, platinum, diamond, and synthetic sapphire. The piece holds a central old European cut diamond weighing 0.73 carat within an octagonal bezel, flanked by two trillion cut synthetic sapphires in blue. Detailed elements include milgrain borders, intricate filigree metal work in the gallery, and fine engraved shoulders along the slender shank. The photograph shows a textured white surface beneath the ring, bright silver reflections on the faceted metal shoulders, and deep blue saturation in the triangular side stones. The ring spans 8.65 mm at its widest point and sits 6.2 mm from the finger, with a total weight of 2.67 grams. It functions as a fine personal jewel worn on the hand during daily life or formal occasions today.

FAQs

Art Deco style jewellery, created during the 1920s and revived in mid-20th-century design, is characterised by geometric shapes, contrasting gemstone colours, and intricate surface work such as milgrain edging.

These rings are traditionally constructed using white precious metals such as platinum or white gold, housing brilliant or old European-cut diamonds alongside calibre-cut sapphires.

Authentic vintage pieces feature hand-engraved detailing, milgrain borders, period hallmark stamps, and traditional stone settings such as bezel or grain mountings.

A vintage sapphire and diamond ring functions as a central accent piece that pairs with modern tailored clothing or formal wear, effortlessly stacking beside plain metal wedding bands.

Clean the ring using warm water, mild soap, and a soft toothbrush, avoiding harsh chemical cleaners or unverified ultrasonic treatments to protect delicate mountings.
