1. Any of the stones can disappear when used as projectiles by means
of kicking and hit a monster. (So there is a 50% chance you have just
ruined your luck buddy.)
2. None of the stones can disappear this way. (Have a good look around
for an undetectable brainless creature that is carrying your stone or
another level teleport that whoever's got the stone has stepped on.)
3. Only flint stone can be destroyed by kicking. (Relax, most likely
what you've got is the valuable one.)
Many thanks.
Yes, I think this is the case, but I the probability is neither
50% nor fixed, AFAICT. (Avoid hitting the monsters. And, BTW,
throwing the quest artifact luckstone at your quest leader, as
a special case, won't destroy the artifact.)

No, I suppose there's no further distinction; both, stones and
gems, are considered being of the same gem-class type for that
purpose.

There is a source code comment magic stones cannot disappear. I'm not
sure about flint stones.

The most likely explanation is some magic-liking monster picked it up.
I think mostly (only?) brainy monsters have the "likes magic"
attribute, so you stand a good chance of finding the stone with
telepathy. Don't rely on object detection in this case: it shows only
one object per monster, and I don't know which one.
What would really suck is if that monster stepped on a level teleport
trap.
But luckstones aren't considered magic, are they?
Janis
They are. http://www.steelypips.org/nethack/343/wan2-343.html#magical
Ah, I missed the flag in objects.c but it is there, indeed. Thanks.
Janis
I think it's a good idea to explore the entire level again to look for
it and/or for a monster carrying it.

Are objects effected by level teleport traps? I thought the "It hits
it" meant the trap just teleported the luckstone to a random level.
Exploring top to bottom would suck.
It (the projectile) hits it (a monster). No traps involved. My guess
is: the "targeted" monster picked up the luckstone projectile right
away. If the monster hadn't, Paulus probably wouldn't have asked on
RNG where the stone is.
If the RNG was especially mean to him, that monster later stepped on a
level teleport trap. Objects in a monster's inventory are of course
affected by levelport traps that whisk the monster away.
While we're at it, AFAIK the only objects that can be teleported in
their own right by a trap are boulders.
If the RNG would have been especially mean to him, a monster would
have stepped onto a polytrap, became a black dragon, and disintegrated
the monster with the luckstone that's residing in between you and the
dragon. ;-}
My tame dog once picked up my BoH and got disintegrated that way. :-(

If you want a spoiler on identifying objects in general and gems in
particular here it is -
http://www.steelypips.org/nethack/id_faq.html#gems
It starts with methods to identify gray stones by type.
A bit on having more than one luckstone - Blessed ones stop positive
luck from decaying. Cursed ones stop negative luck from decaying.
Uncursed ones stop either type of luck form decaying. If you have more
than one in your open inventory the majority wins. If I ever end up
with two I like to carry a blessed one in my open inventory and another
blessed one in the bag. If the one in my open inventory is no longer
blessed I swap which one is in the bag and bless the next time holy
water is available.
