 SCP-472 is a red garnet of the pyrope spesartite variety. The phrase, for man looketh on the outward appearance, but the Lord looketh on the heart, has been engraved in two millimeters, high lettering on the stone's surface. Relevance of the phrase is unknown. When any organism possessing a heartbeat passes within an 18 meter or 60 foot radius of SCP-472, that subject will begin to hear the distant beating of a heart within their head. The heartbeat heard directly corresponds with the subject's own heartbeat, with the frequency of the palpitations increasing or decreasing with the pulse of the subject. Prolonged exposure causes a variety of additional psychological effects.
