French Blue Opaline Bowl with Heavy Gold Gilding

19th century authentic blue gold banded French opaline, opalescent, bowl with heavy gold gilding. From the 1800s. It measures approx. 7.5 inches across and 2.5 inches tall. In excellent condition with very little wear to the gold gilding. The translucent glass looks like it would glow under a black light like vaseline glass, but I don't know for sure. Circa 1800s.
