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
