hello Sammiten
it always helps if you can indicate dimensions either in the image (with a ruler or coin) or in your description-
i guess they are less than an inch long?
i have some of similar shapes that are Czech, on 1940s short necklaces. your mixed colours are attractive!
if they were indian they would have remnants of chalky white stuff coating the inner surface of the hole...

Hi, they are about right on an inch long and they were harvested from a very tired looking 1950’s necklace so 1940’s would be bang on!
