Blue Sapphire
The Heaven-Blue Keeper of Truth’s Voice
About the stone

Blue sapphire is a variety of corundum whose rich blue color comes from traces of iron and titanium. Treasured since antiquity and worn by royalty and clergy for centuries, it has no single recorded discoverer or first discovery date; its name derives from the Greek sappheiros, a term that probably originally referred to lapis lazuli. Important sources include Sri Lanka, Myanmar, Madagascar, Tanzania, and Australia, while Kashmir is historically famous for exceptionally velvety blue stones. In traditional lore, sapphire symbolizes truth, nobility, and faithfulness; ancient Greeks and Romans believed it protected against envy and harm, while medieval clergy associated it with Heaven.

Care and handling
Blue Sapphire is very hard and durable, but a sharp blow can still chip or split it along weak planes. Clean with warm water, mild soap, and a soft brush, then dry. Many sapphires are heat-treated or fracture-filled, so avoid ultrasonic cleaners, steam, and harsh chemicals, which could damage a filling. Store it apart from other gems, since it can scratch softer stones. Check with the seller if you are unsure whether a stone is natural, treated, or lab-grown.
Individual experiences with Blue Sapphire vary, and its associations with wisdom and truth are cultural traditions. Wear or hold it as a reminder to speak honestly, think clearly, and keep your commitments.
