Irresistibly beautiful, they are mined from a single source, which is situated at the foothills of Mount Kilimanjaro. The Tanzanite embodies all that is wild, precious and beautiful about Africa. Peter Gilder is one of only a handful of jewellers to have visited the mine and can answer any of your queries with first hand knowledge – providing insight that is extremely rare in the jewellery retail environment.
