Description

Beautiful Art Deco 18ct Gold Sapphire and Diamond Engagement Ring. Lovely quality Ring consisting of a large 7 x 4mm rectangular velvety blue coloured sapphire. the sapphire has been tested as sapphire but could be synthetic as it has no flaws at all.. This reflected in the price. The sapphire is surrounded by 12 sparkly quality round cut diamonds of 3 points each. Total diamond weight 0.36ct min, all stones set into platinum. The face is beautifully designed in a soft rectangle shape measuring 12mm x 9mm. The total face of the ring is 12mm x 9mm. Well made quality ring in very good condition, the white sparkle of the diamonds and the colour of the sapphire have wonderful life and a timeless romantic feel. Would make a wonderful classic engagement. Shank is fully hallmarked for 18ct gold, platinum and also the word 'LIFETIME' but no date stamp and probably dates to around the 1950s. This ring is size UK L and US 5 1/2 Weight 2.9g

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric symmetry, clean lines, and a heavy influence from industrial design and modernist art.

Authentic pieces from this era frequently utilised 18-carat yellow gold, platinum settings, natural sapphires, and old European-cut diamonds.

Authenticity is typically determined by hand-cut gemstones, period-appropriate setting techniques such as milgraining, and hallmark stamps indicative of early 20th-century assay offices.

Vintage rings can be worn as standalone statement pieces or stacked with contemporary minimalist bands to create a contrasting, curated look.

Clean these items gently using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners which can damage historical settings and treated stones.
