Art Deco Square Halo Ring
An Art Deco cocktail ring that plays on dualities:
presence and delicacy; square and circle; precision and imperfection; organic and artificial; warm and cool, shimmer and shine...
A diamond-studded square with fine millegrain borders frames a gorgeous white pearl with a radiant, golden overtone and iridescent orient. Square and circle. Warm and cool. Shimmer and shine.
The naturally imperfect pearl - not quite spherical, the surface not quite smooth, grown inside a living organism - is the perfect foil to the diamonds' crisp cut facets, and lines and right angles, the clean geometry, of the platinum ring. Precision and imperfection. Organic and artificial.
The aesthetic is quintessentially Art Deco, circa 1930, distilled to its simple essence. Presence and delicacy.

Condition
We offer detailed and accurate condition reports on each listing. These pieces are antique, vintage, or pre-loved and often over 100 years old so they're going to have lived a life. A healthy patina and the odd scuff or scrape is quite normal... it's part of their charm! Everything we present has been checked over by our jeweller and should be good for wear for many years to come (unless otherwise stated) but please remember to treat them with appropriate care and consideration for their age.
