Unless the yellow beads happen to be less than twenty (20) years old, I doubt that China is a candidate for having made such trail-decorated glass beads. Stef—can you cite an instance of similar products?

My first thought was that these are Venetian beads. However, looking closely, what they appear to be (to my eyes) are beads that imitate Venetian beads. They have some congruency to Japanese beads (probably post-WWII). And, of course, we know that some Venetian beads have been copied (sometimes impressively-so) in Java. Also mostly over the previous twenty (20) years.

I certainly agree with your sccessment of the molded Czech beads.
