Saphirus tante virtutis est quod gemma gemmarum vocatur, colorem\ habet firmamenti, quando sine nube est, et dicitur sercites quia in harena\ Libie pre sirtes invenitur, hic clarus, sed ille melior qui invenitur apud Turcos,\ licet non adeo clarus, eius virtus confortat ferentem, membra conservat\ integra, invidiam et fraudem vincit, aufert timorem, et educit de carcere,\ solvit vincula. Interficit antracem, infrigidat hominem supra modum cale\factum interius, tritus cum lacte servat malagmata, utilis oculis, malo lingue\ dolorem aufert capitis, et qui fert caste ferri debet.\
Smaragdo viriditate vincit omnia, sex habet species, quidam de Sci\cia, de Britannia [Bactriana], quidam de Nilo qui currit de Paradyso, quidam iuvenis [in venis]\ matalli [metalli] invenitur, et quidam vocatur Calcidonia, qui de Scicia, et adeo clarus\ ut possit visu penetrandi, et qui retinet aerem sibi proximum melior est,\ nec mutat colorem propter solem vel lunam vel umbram et lapis talis planus\ bonus est ad visum, sicut consuevit et Nero, per hanc adquiruntur res in aquis\ per hanc accrescunt divicie si caste feratur, confert eloquenciam acceptabi\lem si collo feratur, sanat febrem emitriciam, guttam caducam aufert, tem\pestatem et luxuriam et eciam colorem accipit, si discoloretur et lavetur\ vino et unguatur oleo viridi privat colorem. \

Sardonius ex duobus lapidibus nomen habet, et ex hiis tres colores.

he is not bitten; remove the stone and the flies bite him ceaselessly. There are seventeen kinds of jasper; it has many colours; and it grows in parts of Sicily. The green and translucent kind is better and of more virtue than the rest. Jasper defends any chaste person wearing it from fever and the dropsy, and from apparitions; it strengthens friendship, keeps you safe and gives you courage. It is of greater virtue if set in silver rather than gold.
Sapphire is of such virtue that it is called the gemstone of gemstones. In colour, it is like the sky when it is cloudless. It is called serc[t]ites because it is found on the shore of Libya in front of sandbanks. This kind is clear; but a better kind is that found in the land of the Turks, although it is not so clear. Its virtue strengthens him who wears it, preserves his limbs intact, overcomes envy and deception, takes away fear, brings him out of prison, and loosens his bonds. It gets rid of an ulcer and cools you if you are overheated internally. Ground up with milk, it serves as an emollient; it is good for the eyes and for an injury to the tongue, and it takes away a headache. If you wear it, you should behave in a chaste fashion.
Smaragdus surpasses everything in its greenness. There are six kinds: from Scythia, from Britannia [Bactria], from the Nile, which flows from Paradise; one is found in the veins of mines; one is called Chalcedonian. The one from Scythia is so clear that you can see through it; it colours the air around. It is the better kind. Smaragdus does not change its colour on account of the sun or moon or shade; it is so even that you can look through it, as Nero used to do; you can use it to find things under water. It brings wealth if it is worn chastely; it endows you with persuasive eloquence if it is worn on the neck. It cures fever; it gets rid of the hemitertian fever and epilepsy; and it banishes storms and wantonness. It also takes on colour: if it is discoloured and washed in wine and anointed with green oil, the discoloration is dissolved.
Crisapacion comes from Ethiopia; its colour is like gold and at night it shines like fire etc.
Sardonyx gets its name from two stones, and from these it gets three colours. Its first colour is black; above the black is white; above the white is red. This stone has five types, but the one which has the three colours not mixed together is worth more. It does not stick to wax; it has no other virtue, but you must be chaste and humble for it to have this virtue. The stone comes from Arabia and India. If worn on the neck or finger, it brings deep sleep, cures strife and also makes infants somewhat sharp-sighted. There are five kinds.
