Sard gets its name from the island where it was first found; it is red in colour; the least valuable of gemstones, it has no virtue other than its beauty and the fact that it removes the harmful effect of the onyx stone. There are five kinds.
Chrysolite resembles the water of the sea and has a grain of gold within it, and sparks like fire. Its virtue is to counter night-time fears; if it is pierced, with the hair of an ass placed in the middle, and worn on the left arm, it puts demons to flight. It is found in Ethiopia.
Beryl has a hexagonal shape to give it greater clarity; the better kind has the colour of oil or sea water. It is found in India. It bestows love between a man and a woman; it brings honour to him who wears it; it warms the hand of anyone who holds it; water in which it has lain is good for the eyes; and it takes away asthma and the pains of fevers. There are nine kinds.
Topaz gets its name from the island, Topazos, where it is found. It is valued more because it has two kinds of radiance: one the colour of gold; the other, clearer. It is quite good for piles; it is said to feel the pull of the moon; and it causes water to stop boiling. It comes from Arabia.
The chrysoprase comes from India. Its colour is like the sap of a leek, with golden marks; but there is nothing on record about its virtue.
There are three kinds of hyacinth. Each one gives strength, and removes sadness and false suspicion. The kind with a watery colour chills you; anyone who wears it on his neck or finger can go in safety in foreign parts and is safe from overeating; he will be honoured by his enemies and anything he seeks in a righteous fashion, he will receive. The stone cannot be engraved.
The amethyst is the colour of a violet or a drop of red wine or whiteish. It comes from India. It is easy to shatter. If it were rarer, it would be more valuable. There are five kinds to look for.
Chelidony is a stone. It is found in the stomach of the swallow; it has two colours, black and red; the black kind is helpful to the insane, heals demonic possession and other kinds of weakness; it makes a man eloquent and loved; it should be worn on the left arm wrapped in a linen cloth.
The red kind helps to bring things to completion; it offers protection against the threats and rages of kings and princes; if it is moistened in saffron and worn in a linen cloth, it heals anyone with a fever and restrains noxious humours.
Jet comes from Lycia. The better kind is found in England. When it is made warm it attracts straw; it burns
