A specimen of corundum var. blue sapphire tumbled pocket stone.

Blue sapphire is a variety of corundum, an aluminum oxide mineral (Al₂O₃). Its rich blue color comes primarily from trace amounts of iron and titanium, though sapphires can occur in nearly every color of the rainbow, known as “fancy sapphires.” With a Mohs hardness of 9 like ruby, sapphire is extremely durable, second only to diamond. It crystallizes in the trigonal system and exhibits distinct basal cleavage. Major deposits are found in Sri Lanka, Myanmar (Burma), Madagascar, Thailand, and Montana (USA).

In metaphysical traditions, sapphire is considered a stone of wisdom, truth, and mental clarity. It is believed to enhance focus, intuition, and spiritual insight. Associated primarily with the Third Eye Chakra and Throat Chakra, sapphire is thought to encourage clear communication, inner vision, and the alignment of personal truth with higher consciousness.
