In Poland on the street I bought fablous amber pin and a small painting at a crafts booth for a few dollars american..they were willing to deal if you paid in $$$$. Also spices on the street in Egypt. Did buy an unset piece of tanizinie in Africa and had a ring made but I don't wait it very much.
I am not a jewlery buff...buy lot of small prints and painting to line the walls of the stairwell..I see them every day to reming me of the adventures and mis-adventures!!!
