The latest edition in our Gemstone saga is about one of the rarest and most diverse gemstones in the world - Tourmaline.
A gem of many colours, Tourmalines have been misidentified as emeralds, rubies and diamonds down through the centuries.
We discuss some of the most famous Tourmalines in history and, as always, discuss the ins and outs of identifying and valuing this gem!
