Vintage Diamond & Camphor Glass Ring


Camphor glass was made to echo the look of rock crystal. It is blown or pressed clear glass which was then exposed to hydrofluoric acid vapors to develop its characteristic frosted finish. The traditional starburst pattern was either cut into or embossed on the back of the glass. The popularity of camphor glass reigned from the mid 1800s through the 1930s.

A rectangular plaque of frosted camphor glass is set into an open work ornate 14k white gold mounting. The octagonal geometric shape typically associated with Art Deco lends itself quite well to the medium. A small single cut diamond is centered within a lozenge and appliquéd upon a series of graduated or stair stepped lines of white gold. Corners are embellished with open trefoil elements. Please note that the starburst effect is visible through the front and accentuates the centered detailing. Designed and manufactured by the Untermeyer-Robbins Company of New York. The firm was an importer of diamonds and a manufacturer of platinum and gold rings, watch cases and bracelets.

Date: Circa 1925.
