Dear Barry, When I was last in South Africa, several years ago, there
was a jewelry supply house and a rock shop in downtown Pretoria.
They were only a block apart. Both of the operators were well
informed and congenial. You might find them to be somewhat helpful.
There is also a rockhound magazine and it too would be a starting
place for networking inasmuch as it has many names of people and
businesses that are active in yur area of interest. There is also a
flea market near the Johannesburg airport where you might find some
people involved in the business. Also in Jo’burg there is a very
nice flea market near the Holiday Inn Motel which has a large
assortment of things African. This area is quite safe whereas
downtown Jo’burg has a reputation for being
somewhat risky. Happy noodling Ron at Mills Gem, Los Osos, CA.
