Beautiful ladies spittoon or vase

Made in the very early 1900's

This paticular one is made out of Vaseline glass and it does glow under a blacklight.

There is a line running across it that I believe is a shear mark as it does not go the whole way through.  It is possible that it's a slight crack, but the piece is solid. There is no indication that the structure of the vase is affected at all. 

(please see last picture)

Two of the petals have black marks on the tips.
