Any clue what these might be?

Antique, from France. Age unknown. Offered for sale online so only photos available. I’m more curious than tempted.

according to the almighty google image algorithm, it is sandwich meat!

Beautiful! It is a gamble, since even though they're old, they could still be synthetic (glass, early synthetics such as spinel/sapphire, etc.). If the price is right though, might be worth the gamble!

I think if they were rolled up with some prosciutto and provolone, they would be tasty...and crunchy!

They look like stones used for costumes or garments. I suspect not real gems. The box does not look like it is from a jewelry business.

Lambskin may be right. Plus, I can the blue paper through windows in the stones. Probably glass.
Maybe for costume jewelry manufacturing?
