Dining Table with 8 chairs

Hello, 

All I know but this set, is that it's all handmade in Africa, Zimbabwe in late 80's, and it was a personal request. Probably it's Mahogany wood. It's a really heavy furniture in excellent condition. 

Any help on what this might cost, or if someone has a reference of same kind of furniture, or if someone can understand more about the wood, it would be amazing. 

Thanks a lot, 

Dimitra
