PC on Crystalline sword

I know there is a sticky with Chrys prices but I'm still having a real problem gauging the value of this sword, I can’t see where it would fall within the guide prices, it has a low req but the bonus is +15% when the max for "while hexed" is +20%.

Grape
Max damage
req 8
+15% While hexed.
No upgrades of any worth.

Any ideas?

despite it's unpopular dmg mod and it's purple

1 Mil but not completely sure

Purple Chryst with that mod ??
100kish max
