Jacynth, strengthens the heart being either beaten into powder, and taken inwardly, or only worn in a ring.
Sapphire, quickens the senses, helps such as are bitten by venomous beasts, ulcers in the bowels.
Emerald; called a chaste stone because it resists lust: being worn in a ring, it helps, or at least mitigates the falling sickness and vertigo; it strengthens the memory, and stops the unruly passions of men.
Ruby (or carbuncle, if there be such a stone) restrains lust; resists pestilence; takes away idle and foolish thoughts, makes men cheerful. Cardanus.
Granite. Strengthens the heart, but hurts the brain, causes anger, takes away sleep.
Diamond, is reported to make him that bears it unfortunate.
Amethist, being worn, makes men sober and steady, keeps men from drunkenness and too much sleep, it quickens the wit, is profitable in huntings and fightings, and repels vapours from the head.
Bezoar, is a notable restorer of nature, a great cordial, no way hurtful nor dangerous, is admirably good in fevers, pestilences, and consumptions, viz. taken inwardly; for this stone is not used to be worn as a jewel; the powder of it put upon wounds made by venomous beasts, draws out the poison.
Topaz (if Epiphanius spake truth) if you put it into boiling water, it doth so cool it that you may presently put your hands into it without harm; if so, then it cools inflammations of the body by touching them.
