Generation
All Archeologists start the game with an identified uncursed touchstone.
The shopkeeper of a jewelery shop is always generated with a touchstone.[1]
Description
Touchstones are used to identify valuable gems (including other gray stones), either directly or informally: Applying a touchstone to a gem, or else rubbing the gem on the touchstone, will produce a different message depending on the gem and the touchstone's beatitude.
If you are not blind, a valuable gem will leave streaks of that gem's color on an uncursed touchstone, while worthless glass will instead leave scratch marks; rubbing either type of gem on another gray stone will leave colored scratch marks.[2] A cursed touchstone has a 1⁄5 chance of shattering gems that are rubbed on it.[3] A blessed touchstone will immediately identify the gem and auto-identify itself - an Archeologist or a gnome in any role can use uncursed touchstones as though they were blessed.[4]
Any item made of iron will produce a signature "scritch, scritch" noise when a touchstone is applied or rubbed against it - and any gem will produce the same message if you are blind while using the touchstone. Using a touchstone while hallucinating will produce YAFM without identifying the gem.
Strategy
Touchstones can significantly ease inventory management even when uncursed: worthless glass can be informally identified, type-named and then subsequently discarded to save space in your pack or bags, allowing you to at least save resources in formally identifying valuable gems by other means. A blessed touchstone allows you to sell fully-identified valuable gems for full price and get the full Luck bonus for throwing them to unicorns.
Touchstones also have some limited use in distinguishing iron items from others in their object class using the signature noise that applying one produces. This can be used to informally identify gauntlets of power and kicking boots, or else eliminating them as the identity of non-iron gloves and boots, though gauntlets of power can also be worn to auto-identify them if they are known to not be cursed.
Identification
The most reliable means of identifying a touchstone is to apply it to an iron item or rub the item on it, ensuring you are not blind - it will produce a signature "scritch, scritch" as mentioned previously. Price identification is also reliable for identifying touchstones, as they are the only gray stone with a base price of 45zm.
While hallucinating prevents you from actually using a touchstone to identify gems, attempting to do so will produce a specific message that can indirectly identify an uncursed gray stone as a touchstone.
History
The touchstone first appears in NetHack 3.4.0.
