Origin of sapphire

First recorded in 1250–1300; Middle English saphir(e), saph(i)er, from Old French safir(e), saffir, saffer, from Latin sapphīrus, sappīrus, from Greek sáppheiros, perhaps “lapis lazuli, lazurite, sapphire,” probably from Semitic (compare Hebrew sappīr, and probably a loanword in Semitic); sappīr and related Semitic forms perhaps come from Sanskrit śanipuriya “dear to (the planet) Saturn,” equivalent to Śani “(the planet) Saturn” + priyá- “dear”; further origin uncertain

What does sapphire mean?

Sapphire is a transparent gemstone known for its deep-blue variety.

Sapphire belongs to the corundum family of minerals. Sapphires come in a variety of colors (including completely clear), but if a color is not specified, the word sapphire usually refers to the blue kind. This is the most well-known and is classified as a precious gem, meaning that it has a high commercial value. Some varieties of sapphire, like the one known as star sapphire, are considered even more valuable.

Sapphire is popular in jewelry. It is one of the birthstones for the month of September. It is associated with the zodiac sign of Taurus.

Some sapphires are synthetic, meaning they are manufactured, as opposed to being formed naturally. Due to its hardness, synthetic sapphire is used in a variety of practical applications, including as a material to make windows, lasers, and circuits. It is sometimes used as an abrasive, which is a material used for grinding and polishing.

The word sapphire is also sometimes used to refer to a deep-blue color.

Example: If I had the money, I’d buy that deep-blue sapphire ring.

Where does sapphire come from?

The first records of the word sapphire come from around the 1200s. It comes from the Greek sáppheiros, which may have referred to lapis lazuli, lazurite, or sapphire itself. The earlier Semitic form sappīr may come from the Sanskrit śanipuriya, meaning “dear to (the planet) Saturn.”

Sapphire occurs in many igneous rocks and is a variety of the mineral corundum, which is a form of aluminum oxide and is one of the hardest known substances. The red variety of corundum is known as a ruby, another precious gemstone. The blue coloring of sapphire is due to small amounts of iron and titanium.
