9mm Marigold yellow / neon orange silver lined bugles antique Murano glass beads vintage Italian blacklight UV reactive glow

10 gram package. Approximately 9 mm each.

These stunning marigold silver lined beads have a superpower: they glow bright orange under 365nm uv light (black light)! And they are gorgeous under regular light, too.

The two commonly used frequencies of black lights are 395nm (most common) and 365nm. These particular beads have a minimal reaction under 395nm (picture #3), but they're super bright under 365nm (picture #4). Please note the difference before purchase.

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.
