Adamantine
Adamantine was a jet-black alloy of adamant and other metals. Usually black in color, adamantine had a green sheen when viewed by candlelight or a purple-white sheen when viewed by magical light.[2]
It was found only in veins of ore near earth nodes and areas of faerzress in the Underdark.[citation needed] Occasionally, small meteorites consisting of some adamantine would fall to Abeir-Toril as well.[4][1]
Adamantine
This alloy, of five-eighths adamant to two-eighths silver and one-eighth electrum (itself a natural alloy of silver and gold) retains the hardness of adamant, but combines it with a rugged durability that makes adamantine so hard to shatter that it is the favored substance for the making of war hammer heads, the best nonmithral armor, and harbor chains. (By one of the miracles granted by the gods, adamantine can also be derived by combining steel and mithral if one knows how. Adamantine is black, but has a clear green sheen in candlelight a sheen that sharpens to purple-white under the light given off by most magical radiances and by will-o-wisps.
Adamantine is tricky to make, and must be forged and worked at very high temperatures by smiths who know exactly what they are doing and who have access to special oils to slake and temper the hot metal in. Almost all such expert smiths are dwarves, as the Deep Folk guard the secrets of working adamant jealously, but a priest or wizard seeking to enchant items can make use of finished adamantine items and need not necessarily have to work with a smith to create an adamantine work anew.

Adamantine readily takes enchantments, adding a +2 bonus to all saving throws of awakening, enchant an item, holy vesting, and wondrous web spells cast upon it. It is often the primary material for enchanted armors.
Items made primarily of adamantine automatically succeed in all item saving throws vs. normal fire, cold, and electricity. They receive a +4 bonus to all item saving throws vs. acid, crushing blow, disintegration, fall, magical fire, and lightning.
Found deep in the Underdark or rare meteorites.
Adamantine
[AC 23] (DMG)
Some folk in Faerûn believe that metallic adamantine is made by combining adamantine ore and the correct proportions of silver and electrum, or even by combining steel and mithral, but dwarves and others in the know scoff at such tales. Found only in meteorites and the rarest of veins in magical areas, this ultrahard metal adds to the quality of a weapon or suit of armor based on how much of the material is used. Thus, adamantine plate offers a greater increase in protection (as well as a higher cost) than adamantine chainmail, and an adamantine battleaxe offers a greater increase in offensive capability than an adamantine dagger. Weapons fashioned from adamantine have a natural enhancement bonus to attack and damage. Armor fashioned from adamantine has a natural enhancement bonus to AC. These bonuses do not stack with any other enhancement bonuses. Thus, an adamantine (+2) sword enchanted with a +5 enhancement bonus effectively has a +5 enhancement bonus. In an area where magic does not function, it still retains its natural +2 enhancement bonus. Weapons and armor fashioned from adamantine are treated as masterwork items with regard to creation times, but the masterwork quality does not affect the enhancement bonus of weapons or the armor check penalty of armor.
Adamantine has a hardness of 20 and 40 hit points per inch of thickness.

An alloy of adamant (a strong but brittle metal), silver and electrum. Adamantine is black, but has a clear green sheen in candlelight – a sheen that sharpens to purple-white under the light given off by most magical radiances and by will-o-wisps.
Adamant
This is the pure metal form of the hard, jet-black ferro magnetic ore known as adamantite, from which the famous alloy adamantine is made. Adamant is rarely found in nature, but when it is, it is always be in large spherical pockets in hardened volcanic flows. Adamant is one of the hardest substances known, but it is also brittle. A sword made of adamant could slice through most metals but would snap off if struck by another blade or even a smartly wielded wooden cudgel.

Adamantine
Note: Adamantine, which is often found in azer mines.
The following information is from Xanathar’s Guide to Everything
Adamantine Weapons
Adamantine is an ultrahard metal found in meteorites and extraordinary mineral veins. In addition to being used to craft adamantine armor, the metal is also used for weapons.
Melee weapons and ammunition made of or coated with adamantine are unusually effective when used to break objects. Whenever an adamantine weapon or piece of ammunition hits an object, the hit is a critical hit.
The adamantine version of a melee weapon or of ten pieces of ammunition costs 500 gp more than the normal version, whether the weapon or ammunition is made of the metal or coated with it.

History & Usage
Discovery
Mines
Natural adamantine was mined in the following places in the Realms:
Greypeak Mountains[7][6]
Everyday use
Adamantine, when smelted, was ultra-hard but this was a costly procedure.[1] Adamantine weapons were useful for damaging the weapons and armor of opponents. A set of adamantine armor or a shield was nearly impenetrable to normal weapons.[citation needed]
Adamantine was often used by drow elves of the Underdark, and their adamantine weapons were usually swords that were magically enhanced. Their magical strength and sharpness faded if brought into contact with direct sunlight.[citation needed]
The githzerai used their knowledge of Limbo to bring a shard of it when they traveled to the Prime Material plane. A group of anarchs then molded that essence of Limbo into large adamantine citadels that served as remote bases from which to observe enemies or to launch attacks.[5]
Manufacturing & Products
Production
Naturally occurring adamantine was mostly found in meteorites and rare mineral veins.[1]
Adamantine was extremely difficult to produce, requiring high forging temperatures and a very delicate procedure. As an alloy, it was composed of five parts adamant, two parts silver, and one part electrum. Most smiths that specialized in producing adamantine were dwarves,[2] particularly those from the ancient kingdom of Ammarindar.[6]
It was also possible to produce adamantine as an alloy of mithral and steel through the application of several magical procedures, although the process to do so was exceedingly complex.[2]
