It bestows health and riches, grants the gift of prophecy and good memory, and excellent luck in commerce. ### Physical Description A green gemstone variety of beryl, counted as one of the four precious gems (with diamond, ruby, and sapphire). The color is caused by trace amounts of chromium or vanadium. Emeralds often have significant inclusions and little brilliancy or fire—consequently, clear, well-cut gems reach high prices. A rare variety, called trapiche, form when the impurities outline the stone's hexagonal crystal structure in a form reminiscent of a cartwheel or a six-armed cross. --- ## Occurrence Like other beryls, emeralds appear mostly in granite pegmatites, mica schists, limestone, and hydrothermal vents. ### Extraction & Preparation Apply special care when mining emeralds—due to inclusions and internal fractures, the stones are very brittle. Treat them with resins or oils (preferably cedar oil) to improve the clarity and stability of the stone. To reduce breakage, cut it into flat stones, cabochons, or pears. Emeralds loses color when strongly heated. --- ## Properties ### Decorative Properties Emerald is one of the most valuable gemstones; its price depends mostly on color and clarity. It befits any jewelry, but for longevity, avoid placing it in pieces with high risk of wear like bracelets. ### Magical Properties As a powerful stone of magical healing, emerald cures diseases when used as an amulet or ingested (powdered, mixed with honey and water). It neutralizes poisons and even blinds venomous creatures when they look upon it. Reversely, it brings rest to tired eyes, restores lost sight, and cures eye illnesses. It strengthens memory and cognition, alleviates pain, and eases childbirth. The curious connection of emerald with sexual relations is so far unexplained: the stone seems to abhor those. It quells passions, promotes chastity, and when worn during the act, distracts and disturbs. Furthermore, its other properties are greatly increased when employed by those who remain chaste. Worn at the throat, emerald multiplies wealth and brings supernatural luck in commerce. No contract will be broken with the bearer of the stone, none will try to rob or deceive them, and the gem will even keep them safe from imprisonment—or let break free if captured. It affects the minds of people around, dissuading them from ever saying a bad word about the bearer of the stone. Placed under a tongue, it grants the powers of divination and prophecy. Submerged in a liquid, it conjures visions of the future upon the surface and allows to read the fates. It is particularly well suited for inquires into financial matters. Emerald, connected closely to the element of water, controls the storms and floods. Use it to conjure or dispel rain, grant fertility to the arid land, and create a nourishing environment full of lush vegetation. The legendary Emerald Tablet—a large piece of clear stone—is said to contain the principles of alchemy, written down by a deity. Whoever unearths the tablet, will be therefore granted secret magical lore, known only to gods .
