We have a Teardrop pendant with rhinestone accent, vintage item.  I would estimate that this item dates somewhere between the 1970's - 1990's.  It is silver tone metal with a teardrop rhinestone accent on the top of the pendant.  It measures about 2 1/4" in H x about 1 1/4" across the widest point.  It is in nice, gently used condition.
