i'm satisfied they are stone, not glass, but would leave it to someone with more gemmological knowledge to id the type of jade or other stone. The shape, and fact that the holes are relatively large may also indicate when they were made...?

you have no need to make any apologies- we all started out knowing practically nothing, wondering who to believe- and now most proper bead research has only begun to happen in the last 50 or so years... with encouragement and contributions often in the form of questions on internet forums particularly this one, Beadcollector.net.
