Description

A unique and ornate antique diamond ring. The cushion shaped old mine cut diamond in the centre is glowingly white and bright. Two trefoil spurs set with rose cut diamonds flank two sides of the centre stone, with a pair of slightly larger rose cuts set immediately next to the other sides of the centre diamond. A sweeping, rose cut set band is topped in silver, leading a curved, fluted 18k rose gold shank.

Accompanied by an independent jewellery report from WGI.

Cut: Old mine cut in the centre. The remaining diamonds are rose cuts.

Colour: The centre is H. The remaining diamonds range from I to J.

Clarity: The centre is SI2. The remaining diamonds range from SI1 to SI2.

Carat: The centre is approximately 0.40 carat, with a further approximate 0.20 carat in the surround.

Condition: We love the oxidisation to the silver, but accept that not everyone else does. Please let us know if you would prefer the silver polished and we'll take care of it at no extra charge.

Circa: 1890.

Size: O (UK) or 7 (US). Free sizing available.

Measurements: The diamond in the centre is approximately 4 x 4.6mm. The ring is 10.25 mm at the widest point and sits 3.9mm from the finger.

FAQs

Art Nouveau jewellery, prominent from roughly 1890 to 1910, is characterised by fluid, organic lines, asymmetrical motifs, and inspiration drawn from nature such as floral and insect forms.

Jewellers during this era frequently combined yellow or rose gold with platinum or silver-topped gold settings to enhance the brilliance of old-cut diamonds.

Authentic pieces typically feature hand-cut diamonds such as old European or rose cuts, handmade settings with subtle irregularities, and period-appropriate metal purity hallmarks.

Antique rings can be worn stacked with contemporary bands to create a mixed-era aesthetic, or showcased individually as a statement piece against minimalist attire.

Regular professional inspections of the prongs are essential to ensure the stones remain secure, and cleaning should be done gently using warm soapy water and a soft brush, avoiding harsh chemical ultrasonic cleaners.
