Bague au Firmament

Bague au Firmament

A rather lovely bague au firmament ring, circa 1780. Such rings, made popular by Marie Antoinette, were known as bagues au Firmament [rings of the Heavens], as the celestial blue ground evoked the night sky and the diamonds twinkled like stars. The high carat gold shank supports a plaque of vibrant foiled cobalt blue glass, a rich blue glass coloured with cobalt oxide to create its distinctive hue and vibrancy. It is set with 17 rose-cut diamond stars, within a surround of rose-cut diamonds, all diamonds set silver. The ring is size M [US 6] and the head of the ring measures 1.5 inches by 3/4 of an inch. Very fine quality and comfortable on the finger due to its curved shape.
