* Metal: Sterling Silver * Length: 20 mm * Width: 10 mm * Finish: Oxidized * Collection: Hearts and Love Celebrate the human heart with this anatomically-correct 20x10x3.5mm heart cast in .925 sterling silver. During the Age of Enlightenment, scientists began to figure out that the heart is the engine of the human body: it powers the bloodstream by beating an average of 72 times a minute and 100,000 times a day. That's 3,600,000 times a year, and 2.5 billion times during an average human lifetime. Treat your heart well, and there's no telling what adventures you'll have! Anatomical heart charms are often used as gifts to medical students, nurses, and new doctors, to celebrate heart surgery patients, and as 'healing charms' blessed by religious figures. Oxidized design on front side only. Height measurement includes 5mm soldered jump ring. Stamped 925.
