Garnet is not only a useful and delicious fruit - a symbol of a cracked pomegranate was used in the heraldry of the Spanish coat of arms. The cracked fruit of the pomegranate meant in the State of Andalusia.
And the Spaniards received a pomegranate (Granada) after a long war of conquest, lasting several centuries beyond the Pyrenees. When the last Muslim state fell - the Granada Emirate, the symbol of the grenade passed to the Spaniards.
The Granada Emirate existed in the Pyrenees from 1228 to 1492.
