NEED HELP!!! LOOKING FOR THIS NECKLACE PLEASE..PLZ

Hey guys my grandmother just passed away and my sister and I found this necklace she used to wear! I need your help. My sister and I can't determine who should get to keep the original, so what we have decided is that whoever can find an exact replica of this necklace gets to keep the original, and the other gets the replicated one, or the same necklace, just not the one my grandmother, herself owned.
