Is This A Chalice?

[Mfhen]

I just got this piece from a store for $30, which the shopkeeper doesn’t know what it is... I am wondering if this is a piece of Chalice. Can anyone help confirm this? Thanks!

i think it's an acan. for $30 that's a steal.

Not an acan...has a different growth pattern than an acan. either a chalice or like DSC said possibly an echinata. It's gorgeous whatever it is!
