Montgomery Wards 24K over Sterling, Diamond cut?

Maybe vintage if it is the box this came in. it does have 925 stamped in the back well.
Montgomery ward closed back in 1999 i think.
Also is this style called diamond cut with the sharp edges?

It was cast,no diamond cut on it.

 

UPCs weren't widely used until the 1980s.

It is hard to tell from my poor photos but the top edges of the petals are all flat sharp cut like. But probably just me.
