Sapphires were a favourite choice in the Middle Ages, though so rare that they were reserved solely for royalty, upper nobility and certain high ranking clergymen. Sapphires were thought to be imbued with magical powers such as protecting the wearer from the effects of poison, preserving chastity, keeping the peace and curing snake bites.
