10/0 Magenta Fuschia UV reactive lined crystal antique Murano glass seed beads vintage Italian Uranium glass

10 gram package. Due to the age of these beauties, the lining shows variegated shades of color, which only adds to their charm.

These beads have a superpower: under UV light, they glow hot pink! Photographed using 365nm and 395nm UV light. It was tricky to photograph them under UV, but the color is amazing, especially under 365nm.

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.

The photo of the bead card shows what one inch of each size of seed bead looks like. Modern beads typically come in sizes 6/0 (not shown), 8/0, 10/0 (not shown), 11/0, and 15/0. There is a noticeable difference among manufacturers, and the diameter/thickness ratio varies greatly in both modern and antique beads, which can cause differences of opinion in sizing. The fourth column shows the delightful variety of sizes formerly made by hand in the storied bead factories of Italy and France, all the way down to 25/0. These beads can be strung with a Size 15 John James needle (not included).

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