i've been asked to identify a number of glass beads some described as "Gabri" beads.

they all look false to me and some definitely recently made in Indonesia.
My understanding is that its a term used for old glass beads mostly found in Afghanistan, but i would love to have some more solid information-

does anyone here have authentic early examples bought as "Gabri" beads, and what characteristics do they display that arent found elsewhere, to compare with the rather strong opaque yellows, greens, reds, blues, whites and blacks used in the ones i have been asked about?
