Cameron, I probably sold garnets and gold nuggets (very few) to that same rock shop in Moscow; can't remember the name.  Owner had a winter house in Sri Lanka and got a lot of gems there before the civil war made it too dangerous.  We also sold him various mineral specimens we "came across" in our wanderings (mostly in abandoned mines).  There was also a local buyer who bought all our antlers, teeth, hides, and game bird feathers.  The scrap metal had to go to Lewiston.
Funny thing is that we always felt cash-poor when we lived there, but when we left, we realized we'd saved up a nice little nest egg....go figure.
Hope you had a great Thanksgiving!
