Interesting facts about Larimar

Larimar is a rare gemstone known for its soft ocean-blue hues with white cloudlike patterns, evoking the calm of tropical seas. It is found exclusively in the Dominican Republic, within the Barahona region, where volcanic activity created cavities later filled by rare blue pectolite mineralization under low-temperature hydrothermal conditions.

First discovered in 1974 by Miguel Méndez and Peace Corps volunteer Norman Rilling, the stone was named by blending Méndez’s daughter Larissa with “mar,” the Spanish word for sea. Since then, Larimar has become a symbol of Caribbean identity and one of the world’s most sought-after rare gemstones.
