Jules Verne,
Celebrated Travels and Travellers…
“ The profit which Tavernier realized from his cargo induced him to resume his travels. But like a wise and prudent man, before starting he learnt from a jeweller the art of knowing precious stones. During four successive journeys from 1638 to 1663, he travelled over Persia, the Mogul Empire, the Indies as far as the frontier of China, and the Islands of Sunda. ”
