Namibia is a great destination for international conferences because of its high standard of infrastructure. The spectacular landscapes, the species-richness of wildlife and the variety of cultures and traditions make Namibia a very popular country to visit.

For gemmologists Namibia is of highest interest because of its unique geology, mineral resources and gemstone potential with diamonds and various coloured stones.
