Original.... See the little flowerettes on either side of the main flower?  They are complete. 

The reproductions are not.

This is original.  See the detail compared to the amber below which is a reproduction.  The detail on the stems of the vines and the flowerettes is a dead giveaway.

This is a closeup of the original (top) and reproduction (below).  Look at the details of the flowerettes and the leaves.  Very obvious when compared like this as a closeup which is which.  Finally and not shown.  If you look at the very bottom, the reproductions have a small bump in the middle where the foot was pushed into the stem (all one mold).  The originals are flat on the bottom, no bumps!
