The sky blue stone's name was coined by a Dominican, Miguel Méndez, who combined his daughter's name Larissa, with mar, the Spanish word for sea. Spring green peridot is the gem variety of ovaline, a silicate mineral thought to be common in the upper mantle of Earth's crust. Peridot-grade ovaline is most abundant in Pakistan and other dry areas. Used as early as 1580 BC in Egypt, peridot is held as a symbol of the Sun.
