There are many of us, even here, who have researched much more widely than the favourite areas of trade beads and others from Africa or ancient Roman, Islamic, etc., and (in my personal opinion)these are much more fascinating just because they arent so popular. Such ones are also often cheap because they dont yet have a reputation for being valued.
While I admire Kiffas, powder glass, etc and collect some examples when I find them, I think even when made with so much attentive skill they are still only curious rather than beautiful, -but, OK, that's just my taste.
