If you want to know, gemstone currently is very popular in Indonesia. I repeat, VERY POPULAR. There, I shouted. At least, this is true in Bandung. Everywhere you see, there's gemstone. Even on the sidewalk, people just open their own gemstone "store" or "boot". ("Lapak", in Bahasa Indonesia.)
I believe, now the gift from Indonesia is "batu akik", the Indonesian's name for gemstone.
To be frankly, I have no idea why gemstone is this popular right now. I've seen people wearing rings with gemstone from as far as I can remember. But, those days, they were not this popular. What causes this popularity?
