2mm Bright yellow opaque antique 2-cut / neon orange antique Murano glass beads Italian blacklight UV sensitive under 365nm black light

10 gram package. Size 2mm antique 2-cut beads: bright yellow opaque.

These lovely short bugle beads have a superpower: they glow under 365nm UV (black light)! And they are gorgeous under regular light, too. Please note that there are different reactions under different types of black light.

The two commonly used frequencies of black lights are 395nm (most common) and 365nm. While these particular beads are a gorgeous deep red orange under 365nm (picture #4), they have a minimal glow under 395nm (picture #5).

In the early 20th century, these rare beads were painstakingly hand manufactured by master craftsmen in the fabled Societa Veneziana Conterie glass factories of Murano, Italy. The slight irregularities in size and shape are an expected and natural result of the production process, which is a lost art.

Nothing shown in the photos other than the beads is included in your purchase.
