Description

Beautiful Art Deco 18ct Gold Aquamarine and Diamond Ring. Superb quality Ring consisting of an excellent coloured old cut aquamarine 7 x 7 mm which is approx 1.25ct. The aquamarine is surrounded by two sparkly old cut white diamonds measuring approx 3mm x 3mm and 12 points each set into a milligrain setting in a classic three stone design. The total face of the Ring measures 14mm x 8mm. The white sparkle of the diamonds and the colour of the aquamarine have wonderful life and a timeless romantic feel. Would make a wonderful classic engagement ring. Ring is in overall very good condition, the stones have no chips and the shank is strong but the platinum on the shoulders has worn down quite alot. Shank is not hallmarked for 18ct gold but has been tested throughout and probably dates to the art deco era. This ring is size UK O and US 7 1/4 Weight 2.5g

Photographs are ZOOMED with x5 magnification. SO Please Check Sizes And Weights before purchasing as JEWELLERY IMAGES ARE ENLARGED!! Dark areas are reflections on the gold.

Please enquire for ring size changes or International shipping. UK postage included in price.

Art Deco jewellery, prominent from the 1920s to 1930s, is characterised by geometric precision, symmetrical designs, and a strong influence from modern industrialism and ancient civilisations.

These pieces typically utilised 18-carat yellow or white gold, often combined with platinum highlights, paired with precious gemstones such as diamonds, aquamarines, sapphires, and emeralds.

Authentic pieces often feature period-specific gemstone cuts such as old European or transitional cuts, hand-carved millgrain detailing, and hallmark stamps indicative of early 20th-century assay offices.

An antique cocktail or engagement ring can be paired with minimalist contemporary bands to highlight its historical craftsmanship without visual clutter.

Aquamarines and older settings should be cleaned using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners or chemical dips that can damage delicate prongs and softer stones.
