In fourth season episode Time Out of Mind, agents of the Abyss are seen wearing this simple cubic pendant, symbolic of the relationship of the Abyss to the Route of Ages, a spatial hypercube tesseract 'where opposites cancel time'. The amulet is also capable of emitting a piercing ultrasonic blast that temporarily disables the wearer's adversaries.
Glossy black cube made of light wood, on a waxed cord.
