make strange crystal to gems

[kmnu96]

strange crystal is always very useless since legacy,

and rustroot is useful to find ore in early stage but it isnt need anymore after.

so i suggest my idea ; gem analyze :

you can analyze strange crystal is just stone like quartz or gemstone.
and use rustroot extract to analyze it.

i don't think much about how about gem usage,
it can be new gilding item, useful curio like pearls, or can setting with luxuries like this crown.

Gems have since been added. Perhaps strange crystal should be one, but I also like it as it is.
