Wikipedia article

Adamantine is by far the most rare and valuable metal in the game. It can only be found in small amounts in mountainous areas. Care should be taken if it is found, since digging down several levels through it will lead you to the demon pits. After you reach the pits, a horde of demons will eventually be loosed on your fortress. These demons are very powerful and can wipe out even a mature, heavily defended fortress.

Discovery of adamantine will also bring the attention of the King, who will immigrate to your fortress once news of your discovery reaches him. If you have not otherwise met the criteria for attracting the King, he will arrive "disguised as a peasant." His requirements appears to be the same in any case, so be prepared!

Location

To start in a location which has adamantine (and the accompanying demon pits), you must start on a mountain tile (∆,∆,▲,▲,▲,▲,^,^,^) or volcano tile (^) in the Region map. The adamantine and pits will be located somewhere within the Local map of that region. It is more likely to be found on a Local map square which also shows as mountain. The adamantine will occupy only one Local square, though the demon pits may extend beyond it. Finding it requires some usage of the Site Finder feature, some cheating, or above-average good luck.

Veining

Curiously, adamantine veins tend to span z-levels more than the xy planes. Finding a short section of adamantine only 2x1 or 3x1, dig up or down a z-level and you'll probably find another short section. So far I have four veins that run 3 z-levels down and along the y-axis before seeming to expand on the x-axis and three viens contained entirely on an xy plane.

Processing

Adamantine strands are extracted from raw adamantine at a craftsdwarf's workshop. The strand extraction labor must be enabled for a dwarf to perform the extraction. The process is extremely slow for an unskilled laborer. Adamantine strands are worth 1800☼ each, while the raw adamantine is worth 750.

Subsequent processing of the strands requires no adamantine-specific skills or labor permissions. Adamantine strands are processed into adamantine wafers at any smelter. Adamantine wafers are worth 1500☼ each - curiously, less than the strands they are smelted from. Adamantine wafers are treated much like bars of other metal, and can be forged into a variety of useful items. Adamantine strands may also be woven into cloth using the Weave Metal Cloth task in a loom. Adamantine strands may be dyed, but if they are melted into wafers the they will return to their normal color and value.

Forging things out of adamantine usually requires three times more wafers than normal; for instance, plate mail normally requires three metal bars to forge; adamantine plate mail requires nine adamantine wafers. Bolts are an exception, requiring only one wafer for a stack of 25 adamantine bolts. Other exceptions to this exist, such as helms. (Maybe someone can make a table using the raws?)

Uses

Adamantine is so valuable that a special message pops up when you discover a vein of it.

Raw adamantine may also be processed into stone goods in the same way as other economic stone. In its raw form, it has a value multiplier of x250 (as opposed to adamantine metal, which is x300). Raw adamantine blocks are worth 1250☼.

Adamantine items are incredibly light: they weigh about 2.5% as much as an equivalent article crafted from iron. Weapons and armor made from adamantine are 5 times stronger than equivalent iron objects.

Adamantine is one of the few magma safe materials. As such, in rock form it can be used to create magma-proof mechanisms.

Storage

Raw Adamantine is stored in stone stockpiles with "Raw Adamantine" enabled in that stockpile's 'other stone' category. However once strands are extracted, they are stored in a cloth pile. If you want to segregate adamantine from plant fiber and silk cloth, adjust the additional options of a adamantine cloth stockpile to allow non-plant/animal products, and all other cloth stock piles to forbid them. Wafers are stored in bar/block piles with adamantine enabled. All other goods can be stored in any stockpile with the adamantine metal enabled.
