SRD said:Adamantine:
This ultrahard metal adds to the quality of a weapon or suit of armor. Weapons fashioned from adamantine have a natural ability to bypass hardness when sundering weapons or attacking objects, ignoring hardness less than 20. Armor made from adamantine grants its wearer damage reduction of 1/– if it’s light armor, 2/– if it’s medium armor, and 3/– if it’s heavy armor. Adamantine is so costly that weapons and armor made from it are always of masterwork quality; the masterwork cost is included in the prices given below. Thus, adamantine weapons and ammunition have a +1 enhancement bonus on attack rolls, and the armor check penalty of adamantine armor is lessened by 1 compared to ordinary armor of its type. Items without metal parts cannot be made from adamantine. An arrow could be made of adamantine, but a quarterstaff could not.
Only weapons, armor, and shields normally made of metal can be fashioned from adamantine. Weapons, armor and shields normally made of steel that are made of adamantine have one-third more hit points than normal. Adamantine has 40 hit points per inch of thickness and hardness 20.
Price Modifiers:
Ammunition +60 gp
Light armor +5,000 gp
Medium armor +10,000 gp
Heavy armor +15,000 gp
Weapon +3,000 gp

is there also anything about shields made of adamantine?
I prefer:Henry said:Kolikeos, a really good site for you to know about would be www.d20srd.org . It's a searchable copy of the whole system reference document (meaning essentially the 3.5 Players handbook / Dungeon Masters Guide / Monster Manual), and includes the Psionics SRD (essentially the entire Expanded Psionics Handbook.
Also, if you have the download bandwidth, Creative Mountain Games sells an Adobe PDF of the entire SRD (soon to be updated to Psionics), and www.andargor.com has a downloadable SRD, searchable, in HTML. All of these are well worth it for rules questions!
Cheers,
Henry
