Larimar is the blue variety of the mineral Pectolite. While pectolite is found all over the world and is not rare, the exquisite sea-blue color of Larimar is unique and comes from one place in the world, the Dominican Republic. Due to its scarcity and limited source, larimar is difficult to obtain. It is a soft gemstone, measuring only 4.5-5 on the Mohs scale. The color of larimar is rarely solid, almost always displaying interconnecting white lines within the blue shade.
