Rainbow Iridescent Glass Heart Pendant

Vintage heart in an old fashioned setting with four prongs. Rhinestone appears to look blue in color, but reflects the light & bounces off colors of golden-green, aqua, turquoise, royal blue and prismatic purple tones. Heart charm & chain set have a lot of battle scars as it's traveled along a journey through life; Discolored chain & minor wear. I believe the chain was 19 or 20", but I added a 2" extension.
