Gem

Gems are simple, (usually) lightweight items you find in the dungeon. They come in three varieties: valuable gems, worthless glass which looks similar, and gray stones. Valuable (identified) gems may be sold for relatively large amounts of money at most general stores, which makes them valuable as a compact form of money. However, shopkeepers will always buy unidentified gems as if they are worthless glass, and will always sell glass as if it were valuable. Valuable gems may also be thrown to a co-aligned unicorn in order to get a large Luck increase. More commonly, since money and Luck are overabundant later in the game, players save all of the valuable gems they find, stashing them away so that they can be added to the player's score upon the completion of the game. Glass and rocks are quite simply worthless, though they can be used for throwing if you should wish to conserve your other attacks. Additionally, they can occasionally be polymorphed into more valuable gems if included in a polypile, though it's not worth wasting a wand charge on them.

Gray stones are a catchall for four different objects until they are identified.

• Touchstones may be used to identify glass from gems, and even the variety of gem if it is a blessed touchstone.
• Luckstones will augment your luck rather impressively; if you have a blessed luckstone and no other luckitems, your good Luck will not timeout, bad Luck will, and you'll get +3 extra Luck.
• Loadstones are a pun (dating back to early editions of Dungeons and Dragons): at 500 weight units, they weigh 50 times as much as the other gray stones, and they autocurse (and are generated cursed) so they can not be dropped.
• Flint stones have no particular purpose, but they do slightly better as sling ammo.

Tables of gems

By value

Some gems' appearances can change. In these cases all the options are listed. The actual appearance is randomly chosen from the options at the beginning of each new game. The hardness of a gem can be tested by #engraving with it; soft gems will only write in the dust.

Fort Ludios

Twelve guaranteed real gems can be found in the corner turrets of Fort Ludios: three diamonds, three emeralds, three rubies, and three amethysts.

SLASH'EM

Due to the existence of migohives, identifying four gems is slightly easier in SLASH'EM, due to the fact that only these gems are generated in migohives- the diamond, the ruby, the agate stone, and the fluorite stone. Hence, if you find a white gem in a migohive and can engrave with it, it's a diamond, and otherwise it's a fluorite stone. Blue, green, or purple gems found in migohives are also fluorite stones. If you find a red gem in a migohive, it's a ruby, and if you find an orange gem, it's an agate stone.
