Æthiopia, which produces hyacinthos, produces chrysolithos ^[Note]

also, a transparent stone with a refulgence like that of gold. The stones of India are the most highly esteemed, as also those found among the Tibareni, ^[Note] provided these last are not of a mottled hue. The worst in quality are those of Arabia, the colour of them being turbid and mottled, and their brilliancy interrupted by cloudy spots: even too, when they happen to be limpid, they have all the appearance of being full, as it were, of a peculiar dust. The best stones are those which, when placed by the side of gold, impart to it a sort of whitish hue, and so give it the appearance of silver. When this is the case, they are set in a bezel that is open on either side; but when the stone is of inferior quality, a ground of aurichalcum ^[Note] is placed beneath.
