Account of the Spinel Rubies

There is another kind of rubies which we call spinel rubies, and the Indians call them carapuch, which are produced in the same country of Peygu, where the fine rubies grow, and they find them in the mountains near the surface of the ground. These are not so fine nor of so bright a colour as the rubies, but they have rather the colour of scarlet: and those which are perfect in colour and pure, are worth half less than the rubies.
