Account of the Hyacinths

The hyacinths are produced in Ceylan, and are soft yellow stones, and those which are of a stronger colour are the best; most of them have within some grains which impair their beauty, and those which have not got them, and are pure, in perfection of this colour, are worth little in Calicut where they arrange them; one which weighs a fanam is not worth more than three fanams, and one of xviij fanams is not worth more than xvi fanams.

There are also other gems, cat's eyes, chrysoliths, and amethists, of which no other distinction is made on account of their being of little value, and so also with regard to the jagonzas.
