According to oriental legend, the earth rested on a giant sapphire, whose blue color was reflected in the bowl of the sky. A variety of corundum colored with aluminum oxide, sapphire is one of the four gems called “precious” today. Its rarity contributed to its reputation as a magic stone of immense and all-encompassing power. It is said to ward off infectious disease, dispel confusion, and to enhance clarity of mind. The sapphire has also been thought since antiquity to bring good fortune to those who wear it. Anyone wearing this rich blue gem will feel very lucky indeed.
