7/0 Crystal/yellow lined antique seed beads UV reactive under 365nm black light Murano glass beads vintage Italian

10 gram package. These charming crystal and yellow beads glow orange under 365nm blacklight. The two commonly used frequencies of black lights are 395nm (most common) and 365nm. These particular beads glow orange under 365nm (picture #3), but they do not have much glow under 395nm (picture #4). Please be aware of this difference.

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.
