“...I got the agate material from Tanzania, Kigoma by Mr Hintze, Jentsch minerals.The material was hand-picked by him. Because the material was recovered near the surface and not very professionally mined, there were barely crack-free agates in the game. These are vein-agates, not agate nodules. According to Mr Hintze, the agates from deeper layers of the host-rock would be even better. Because you can hide this but probably still not professionally, probably for the time being good or even better agates of this site remain barred from us..."
According to a personal message from Andreas Hein. He shows more international and german agates on his homepage heinstein.
