They aren’t just valuable in jewelry, but also in industrial applications, including scientific instruments, high-durability windows, watches, and electronics. The remarkable hardness of sapphires, which measure 9 on the Mohs scale, is second only to diamond.

Their origin can affect their value as much as color, cut, clarity, and carat size. Sapphire gems are found in India, Myanmar, Thailand, Vietnam, Sri Lanka, China, Australia, Brazil, Africa, and North America (mainly Montana). Some believe it originated from the Sanskrit word sanipriya which meant “dear to Saturn.” The name “sapphire” comes from the Latin sapphirus and Greek sappheiros, meaning “blue stone,” though those words may have originally referred to lapis lazuli. Pinkish-orange sapphires called padparadscha (from the Sri Lankan word for “lotus flower”) can draw higher prices than some blue sapphires. In the U.S., these gemstones must meet a minimum color saturation to be considered rubies. Pink sapphires toe a fine line between ruby and sapphire. Sapphires in any color but blue are called “fancies.”

Trace elements like iron, titanium, chromium, copper, and magnesium give naturally colorless corundum a tint of blue, yellow, purple, orange, or green, respectively. Sapphires come in every color except red, which instead earn the classification of rubies.
