I set a vintage vaseline glass ultraviolet cabochon in a silver floral bezel setting. This comes with an 18 inch sterling silver chain. The glass cabochon is 15mm in diameter. It fluoresces bright green under ultraviolet light. 

Czech glass, also known as Bohemian glass, has been made since Roman times. It is one of the most popular types of glass produced. These were made in Czechoslovakia from the 1930s on. Each one was handmade by glass artists in the Bohemian style.

Vaseline glass is often called by many different names including canary depression glass, custard, vaseline, and uranium glass. Trace amounts of uranium dioxide are added to silicate crystals during the melting process to create the bright color. It also glows a fluorescent green under black light. However, it is not radioactive and does not contain enough uranium to be harmful.

Uranium glass was popular from the 1880's to the 1930's. It was sold as tableware and other types of collectables, but production was discontinued when the availability of uranium was sharply curtailed during the Cold War. Most examples of vaseline glass date from that time period. In 1958 uranium was deregulated and it was then produced using depleted uranium. Today uranium glass is mostly made in Eastern Europe.
