Flower blue glass ring called ring of the Heavens or ring au firmament. It is made of yellow 18k yellow gold and set with an oval dark blue glass. A silver flower is decorated by marcasite, inlaid on the blue oval glass on a guilloche background. A Fleur-de-lys motif on the shanks. French work, 20th century.
In the late 18th century and into the 19th century, marquise rings set with diamonds on dark blue or red enamel backgrounds became fashionable in Europe. The oval, like this ring, and the rectangular (shuttle-shaped bezel) were the most popular shapes. They were inlaid with diamonds or other sparkling stones to imitate stars in the sky or floral sprays. As the blue of the ring evokes sky and stars the rings of this kind were called “bagues au firmament” (Rings of the Heavens).
