PC on req10 purple crystalline

Alright, I know that since they are extra rare, even the crappier ones go for nice amounts of plats, but I have no clue about 'exact' prices.

Sundering Crystalline Sword of Fortitude (purple)
slashing dmg: 15-22 (req 10 swords)
+12% dmg in stance
AP +20% (19% chance)
HP +29

Not perfect I know... Any ideas?
Thx...

No ideas at all?

Don't PC if you don't know.

40-60k

Purple crystallines are not "extra rare" perfect gold 15^50 *old skool* crystallines are extra rare.

Kilroy farming killed these.
