Product Details

Stunning Czech uranium glass cabochon with a vibrant neon green glow under UV light. This piece features a faceted cut (unusual compared to traditional smooth cabochons), giving it extra sparkle while still maintaining that classic uranium glass fluorescence. Under blacklight, it lights up bright electric green—true vaseline/uranium glass behavior caused by trace uranium content in the glass, a well-known technique in Czech glassmaking for over a century. Perfect for: • Jewelry making (rings, pendants, wire wraps) • Uranium glass collectors • UV reactive displays • Lapidary / custom settings 📏 Details Size: ~13.9mm x 12.1mm Shape: Cushion / rectangular faceted Material: Czech uranium glass Color: Bright green (glows under UV) Condition: Pre-owned, see photos for minor inclusions
