Larimar Gemstone Handmade 925 Sterling Silver Plated Dangle Earrings Referred to as the Caribbean stone, Larimar is a bluestone composed of the mineral pectolite. Its pectolite, which is found around the world, is rarely used as a gemstone. The blue pectolite has entwined crystals, which makes it hard enough to be used as a gemstone. As one of the most scarce stones in the world, Larimar is found in the Filipinas Mine in Los Checheses of the Dominican Republic. Interestingly enough, this stone is crystallized through minerals that dissolve in hydrothermal fluid from volcanic action. The name Larimar comes from the combination of Mendez's daughter Larissa and the word Mar, meaning sea. Once this gemstone becomes known abroad, its charming blue beauty strikes many hearts and interests.
