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. Another type of item that uses the same glyph is the rock, which is dealt with differently.
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 unidentified gems as if they are valuable. Valuable gems may also be thrown to a co-aligned unicorn in order to get a large Luck increase. Throwing any valuable or worthless gem to a unicorn will pacify them, and will variably raise or lower luck in certain cases. See the unicorn page for more details.
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 relatively 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. Rocks can also be changed in to meatballs, useful for taming and for sale in shops. Arguably the best usage of a worthless piece of glass on early levels is to write Elbereth in the dust, because said glass is accurate if not permanent.
Despite the name, a worthless piece of <color> glass will not shatter like other glass items if thrown against a wall or dropped while levitating.
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 cannot 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.

By color
The gems that have a randomized appearance are marked with an asterisk, "*".
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.
Dipping a valuable gem into a potion of acid will generate another type of potion. The potion you get is defined by its randomized description, not by its identified description- For example, if you dip a ruby into acid, you will always get a ruby potionwhether ruby potions are full healing or hallucination in your game. Note there are no gems that give out milky, smoky or clear potions. There seems to be a chance that any dippage can result in an explosion, as in any alchemy.
Dilithium Crystal -> Always explodes Opal -> Cloudy potion Ruby -> ruby potion garnet -> pink potion Jasper -> Purple-red potion Jacinth -> Orange potion Agate -> Swirly potion Citrine -> Yellow potion Chrysoberyl -> Golden potion Amber -> Brown potion Topaz -> murky potion Emerald -> Emerald potion Turquoise -> Sky blue potion Aquamarine -> Cyan potion Jade Dark -> Green potion Sapphire -> Brilliant Blue potion Amethyst -> Magenta potion Flourise -> White potion Black Opal -> Black potion Jet -> Dark potion Obsidian -> Effervescent potion Worthless glass -> No effect
