How to Identify Uranium Glass Jewelry?

• Verify the signature bright neon green glow using a 365nm or 395nm UV blacklight source.
• Look for the characteristic 'Vaseline glass' oily yellow-green tint in natural daylight.
• Examine metal findings for construction styles consistent with early 20th-century Czechoslovakian manufacturing.
• Check for hand-cut facets or molded bead shapes typical of the 1880s to 1920s peak production era.

History of Uranium Glass Jewelry

Uranium glass, also known as Vaseline glass, has a fascinating history dating back to the 1830s. It was particularly popular from the 1880s to the 1920s. The unique greenish-yellow glow is due to the small amount of uranium oxide added to the glass mixture. Despite containing uranium, it is generally considered safe due to its very low radioactivity. Its production declined significantly after World War II due to restrictions on uranium use.
