Georgian Blue Glass & Old Mine Cut Diamond Bague au Firmament Ring

772H
541 Admirers Rare Find
Written by Olly Gerrish

An unusual Georgian ring that was made circa 1780-1800. It has a curved Bristol blue glass plaque of vibrant foiled cobalt blue glass, which is a rich blue glass coloured with cobalt oxide to create its distinctive hue and vibrancy. It has been set with an old mine cut diamond in a silver pinched setting. The celestial blue ground evokes the night sky and the old mine cut diamond twinkles like a star. This style of ring was known as ‘Bague au firmament” “Ring of the Heavens” and was originally popularised by Marie Antoinette hence the French name
