Happy Valentine’s Day! If you like your celebrations less saccharine sweet, then this heart depicting the chemical oxytocin may be for you. By Etsy seller Delftia, they explain, “Oxytocin, called the “love hormone”, is artistically placed in a heart
pendant to make this metallic expression of love. But don’t worry — oxytocin isn’t just about “touchy feely” love. This organic molecule is also responsible for the more raunchy stuff.”

This piece is silver plated brass and sells for USD$51.
