Larimar is a blue variety of the mineral Pectolite. Pectolite is not a rare mineral and is found throughout the world, but the exquisite sea-blue color exhibited in the Larimar variety is very unique, and only comes from one place in the world. It is found only in a limited deposit in the Dominican Republic, and is virtually the only gemstone to be found in the entire Caribbean. Its lovely sea-blue color is very reminiscent of the Caribbean seas. - See more at: http://www.minerals.net/gemstone/larimar_gemstone.aspx#sthash.THZG97vH.dpuf
