I just find these old glass watch crystals pretty things, especially their labels, and thought surely someone would have creative use for them. The lost includes exactly what you see, with the crystals ranging from in size as indicated by the labels. All appear to be French and a handful are still wrapped in paper, with dimensions printed in blue on the paper. The glass itself shows some dust, but there are no cracks or chips that I can see.

Sold as a lot. Largest crystals measure 1 7/8" in diameter.
