Give your heart to someone! This anatomically correct depiction of the heart is made from gold or silver colored non-tarnish steel and measures about 1" from top to bottom. The science-inspired pendant hangs delicately from an 18" gold plated steel or sterling silver chain, but it is strong enough to last as cherished jewelry for years and years. Whether for yourself or someone special (your sweetheart, your mother, or your cardiologist), this pendant is sure to make an impression.
