Larimar is a very rare Caribbean varient of Pectolite. Pectolites are normally colorless, whitish, grayish or yellowish. For this reason, the blue variant known as Larimar is both curious and unusual on the planet. It exists only in one place. The Dominican Republic. 

The primary (and perhaps the only) semi-precious stone from the Caribbean, Larimar was discovered on or before November 23rd, 1916 in The Dominican Republic. At the time, pectolites were not coveted or well-known on the island, so the request to mine them was denied. 

Later, in 1974, Larimar was re-discovered by two gentlemen; Miguel Méndez and Peace Corps volunteer Norman Rilling. Miguel took his young daughter's name Larissa and the Spanish word for sea (mar) and formed the name Larimar, to suggest the colors of the Caribbean Sea where it was found.

Real Larimar is coveted for it's beautiful blue and white tones which are often described as looking like clouds, the sea, or even lightning.
