I came across a great website this afternoon and just wanted to pass the information on. Kalahari Minerals is owned by Reine Ackermann and he has some very nice African specimens on his site.
 
 
What caught my attention was Reine charges very reasonable prices for his minerals unlike most people. So if you are looking for some unique mineral specimens from Africa under a $100 check Reine’s site out. Also if you happen to be in his neck of the woods he allows visitors to view his collection just give him a call.
