Origin & History of “garnet”

Garnet, as a term for a semiprecious stone, was borrowed from middle Dutch garnate. this in turn came from Old French grenat ‘dark red’, the colour of the garnet, whose original inspiration was probably the pomegranate (in Old French pome grenate), with its vivid scarlet pulp.
