Larimar is a rare variety of pectolite, a silicate mineral composed of calcium sodium silicate. It is known for its distinctive blue to turquoise color, which is caused by the presence of copper. Larimar is typically found in patterns resembling the sky or ocean, with swirling white veins or clouds. It has a Mohs hardness of 4.5 to 5, making it relatively soft and best suited for jewelry or ornamental items with careful handling. Larimar is found exclusively in the Dominican Republic, particularly in the Barahona Province, making it a highly sought-after gemstone.
