(* Each stone is one of 16 colors in the game. Different un-mined stone of the same color have a different symbol to distinguish between them. Once mined, the individual stones themselves can sometimes look identical if the color is the same. Use k to look at items or the terrain for specific information.)

Notes:

Adamantine is not exactly like other metals, although it works almost the same. It has a value multiplier of x300 (yes, three hundred). See (spoilers!) adamantine for a full discussion of this unusual and wondrous material.
% chance for additional metals: when Galena and Tetrahedrite are smelted, they produce (respectively) four lead or copper bars, 100% of the time. They also produce 0-4 additional bars of the second metal, with the percent chance to produce each additional bar listed above.
Ice has some very unusual properties in Dwarf Fortress, and can be disastrous if misused. See the article on ice for a more complete discussion.

The Value of Rocks & Metals[edit]

You won't find the terms "low-value" or "highest-value" used in the game, but they're handy here for rough comparison. "Values" are all relative to each other, on a common scale. The "material value" number multiplies any final product that is created with that material by that number. An average generic statue (base value 25) is worth much more than an average generic throne (base value 10), but a throne carved from raw gold nuggets (10 x 30 = 300) will be worth far more than a common-stone statue (25 x 1 = 25). (Note - "quality" also factors into total value of a final product, as do some other considerations, but those are outside the scope of this intro article). Bottom line - when in doubt, go for the more valuable stuff.

Common stones (the vast majority) have a value multiplier of x1, mid-value (all flux stones like marble) are x2, and high-value (obsidian only) is x3. This affects things like stone tables and doors, statues or stonecrafts - anything made from stone. Metal ores have varying values, from 2-40, and can either be treated as stone or smelted into bars of metal.

For metals, low-value (like copper or nickel) is x2. Mid-value (silver or iron) is around x10, high-value (gold, steel) is x30, and highest-value (platinum, aluminum) is x40.

Note that the raw mined ore and the smelted pure metal often have different value multipliers, but not always. Alloys like brass or bronze are often more valuable than the sum of their pure metal ingredients, and have a true spectrum of values between 3-23. (Alloy values are not listed in this article.)

Any metal can be crafted into decorations, furniture, or buildings. Only copper, bronzes, iron, steel, and adamantine can make weapons, armor, and picks, with silver also able to be forged into melee weapons.

(For comparison, all wood has a value of x1, equal to common stone.)
