Description

Large Art Deco Platinum Sapphire and Diamond Ring. Superb quality Ring consisting of a dark blue sapphire which measures 12x 9mm. The sapphire has great depth of blue colour with zoning to one side which is a lighter shade of blue and indicates it to be a large Natural stone. The sapphire is surrounded by a halo of twelve sparkly old mine cut diamonds measuring approx 2mm x 2.mm and 3 points each set into a milligrain oval setting. Total diamond weight 0.42ct minimum. The total face of the Ring measures 18mm x 14mm. The ring exudes art deco elegance and has a striking contrasting look between the sparkle of the diamonds and the very deep dark blue sapphire. This ring has plenty of WOW factor it would make a wonderful antique engagement ring or a striking cocktail or dress ring. Though in great original wearable condition the ring has a couple of age related condition issues - there is some slight abrading and a scratch to the top table facet which can be seen in the photos. One of the diamonds has a chip to the side. The shank is strong and wearable but has some thinning. These factors are reflected in the price of the ring. No hallmarks but the ring has been tested throughout and most certainly dates to the early art deco era. This ring is size UK N.5 and US 6 3/4 Weight 4.1g

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.

Buy With Confidence: I try to accurately describe my items. I never knowingly mis-sell any item, so please read the description carefully.

Please also note that Antique and Vintage items will show some signs of wear commensurate with age.

In buying a ring which has been in circulation for this long is the most environmentally ethical way to purchase jewellery. Purchasing antique jewellery allows you to both support smaller local businesses and but encouraging the reuse of the vast amount of timeless jewels that are already in circulation and reduces the demand for further stripping of our planets resources.

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric symmetry, stylised motifs, and the frequent use of platinum paired with diamonds and calibrated coloured gemstones.

Platinum became the metal of choice during the Art Deco period due to its strength, allowing for delicate, lace-like settings that securely held diamonds and precious gemstones like sapphires, rubies, and emeralds.

Authentic pieces often feature hand-cut stones such as old European or single-cut diamonds, hand-worked millegrain edges, open-work platinum galleries, and signs of genuine age-related wear on the metal.

An antique cocktail ring serves as a focal statement piece and can be worn alone on the hand to draw maximum attention, contrasting sharply and effectively with minimalist modern clothing.

Antique rings should be stored individually in soft pouches to prevent scratching, cleaned gently with warm soapy water and a soft brush, and inspected periodically by a professional jeweller to ensure stone security.
