AI-assisted summary
Description from the seller
A substantial and striking Art Deco ring with a distinctly architectural character. The ring is built from multiple sculptural bands of warm 14K gold, rising in open, layered tiers around the green tourmaline and contrasting platinum-set diamonds. This unusual construction gives the 6.49 g ring considerable volume and presence while allowing it to sit beautifully across the finger, following the curve of the hand rather than appearing bulky. A bold and exceptionally stylish piece of vintage jewellery.
Hallmark & metal:
The ring is stamped “585” (14K gold) on the inside of the band. The hallmark is partially worn from repolishing over time, but remains identifiable. The ring has also been tested for gold purity. The decorative white-metal sections surrounding the diamonds are platinum. No maker’s mark is present, most likely having been lost through polishing during the life of the ring.
Period:
Estimated production: 1930s–1950s, in the Art Deco / late Art Deco style.
Stone setting dimensions:
The central tourmaline measures approximately 6 × 6 mm, with an estimated depth of approximately 3 mm.
Gemstones:
1 natural green tourmaline — square step cut, approx. 6 × 6 × 3 mm, estimated 0.75 ct. No known treatment. Eye-clean, without inclusions visible under loupe magnification.
Diamonds: 6 natural diamonds — round brilliant cut. 2 diamonds approx. 1.8 mm and 4 diamonds approx. 1.0 mm, estimated combined weight 0.07 ct. No known treatment. Eye-clean, without inclusions visible under loupe magnification. Estimated G–H colour, VS–SI clarity.
Estimated total gemstone weight: approximately 0.82 ct.
All gemstones are believed to be original to the ring.
Condition / restoration:
The ring is in very good vintage condition and has been repolished during its lifetime, resulting in partial wear to the 585 hallmark and likely loss of the original maker’s mark. No other known major damage or restoration.
Shipping & insurance:
The ring will be securely packaged and shipped by tracked and fully insured delivery.
