They had been strung with what appear to be Czech round 3mm black druk beads and an old broken tin box clasp.

I combined them with older? Czech "English-cut" [cornerless cube pressed glass] beads that had been strung on what seems to be yellowed nylon? twist, as it melted into a brown lump with my thread burner tip.

The length allows the two strands to be worn as is, or doubled as a collar-bone length choker.

My clasp selection wasn't quite up to the task - I kind of liked the festive and gaudy faux sapphire, but it's silver colored and I'd already used gold-filled rings for the strand ends and didn't want to restring everything, as it was a hell of a job the first time around, given my worsening eyesight.

So I stuck with a small, old-fashioned looking clasp. A bit fiddly when it comes to the doubled choker arrangement, but it works and the vertical style seems more secure.

Does anyone have a clue when these beads were made, and whether they're Czech or Moretti? The inside colors are produced by a glass tube featuring rounded segments of cyan, yellow, and magenta - just like printer's colors. The overlay is a 5-sided cane. Polishing marks are still visible on the facets.

Recent and vintage Czech glass seems to use red, green, and blue wisps of color, not a base tube.

They look very different depending upon whether the background is dark or light.
