The tumbling action along the streambed provided the natural polishing to the blue larimar, which makes them stand out in contrast to the dark gravels of the streambed. The Bahoruco River carried the pectolite-bearing sediments to the sea. When these rocks erode, the pectolite fillings are carried down the slope to end up in the alluvium and the beach gravels. These pectolite cavity fillings are a secondary occurrence within the volcanic flows, dikes, and plugs. These rocks contained cavities or vugs which were later filled with a variety of minerals, including the blue pectolite. Miocene volcanic rocks, andesites and basalts, erupted within the limestones of the south coast of the island. Pectolite is found in many locations, but larimar has a unique volcanic blue coloration, which is the result of copper substitution for calcium. Larimar is a type of pectolite or a rock composed largely of pectolite, an acid silicate hydrate of calcium and sodium. An upstream search revealed the in situ outcrops in the range and soon the Los Chupaderos mine was formed. The few stones that they found were alluvial sediment, washed into the sea by the Bahoruco River. Méndez took his young daughter's name Larissa and the Spanish word for sea ( mar) and formed Larimar, to suggest the colors of the Caribbean Sea where it was found. Natives believed that the stone came from the sea, and they called the gem Blue Stone. Miguel Méndez and Peace Corps volunteer Norman Rilling rediscovered Larimar in 1974 on a beach at the foot of the Bahoruco Mountain Range, the coastal province of Barahona. Pectolites were not yet known in the Dominican Republic, and the request was rejected. The Dominican Republic's Ministry of Mining records show that Father Miguel Domingo Fuertes Loren of the Barahona Parish requested permission on 22 November 1916 to explore and exploit the mine of a certain blue rock that he had discovered. Its coloration varies from bluish white, light-blue, light-green, green-blue, turquoise blue, turquoise green, turquoise blue-green, deep green, dark green, to deep blue, dark blue and purple, violet and indigo and the larimar can come in many varieties and color mixes. Larimar is the tradename for a rare blue variety of the silicate mineral pectolite found only in the Dominican Republic, around the city of Barahona.
