Sri Lankan sunstone ( Ovl 1.00 Ct). Ethiopian Welo Opal, Jalisco Fire Opal, Tanzanite Pendant With Chain (18 in) in Platinum Overlay Sterling Silver TGW 1.77.  This necklace has never been worn. Still in the gift box it was purchased from HSN or QVC.  I received it in an estate sale with a few more items of jewelry. This is double sided and accent stones are Tanzanite and Sunstone. Very beautiful color and brilliance!!! Very unique and vintage.
