Article: Larimar



  • Father Miguel Domingo Fuertes Loren requested permission to explore and exploit the mine of a blue rock in 1916.
  • Larimar was rediscovered by Miguel Méndez and Peace Corps volunteer Norman Rilling in 1974.
  • The stone was called 'Blue Stone' by the natives.
  • Larimar is a combination of Larissa (Méndez's daughter's name) and the Spanish word for sea.
  • The stones were found in the alluvial sediment washed into the sea by the Bahoruco River.


  • Larimar is a type of pectolite, composed largely of pectolite, an acid silicate hydrate of calcium and sodium.
  • Larimar has a unique volcanic blue coloration due to copper substitution for calcium.
  • The pectolite fillings are a secondary occurrence within volcanic flows, dikes, and plugs.
  • The Bahoruco River carried the pectolite-bearing sediments to the sea.
  • The tumbling action along the streambed provided natural polishing to the blue larimar.

Los Chupaderos

  • Los Chupaderos is the most important outcrop of blue pectolite.
  • It is located in the southwestern region of the Dominican Republic.
  • Los Chupaderos is surrounded by rainforest vegetation and deposits of blue-colored mine tailings.
  • It is a single mountainside with approximately 2,000 vertical shafts.
  • Los Chupaderos is about 10km southwest of the city of Barahona.


  • Larimar jewelry is a local specialty in the Dominican Republic and the Caribbean.
  • Most larimar jewelry is set in silver, but high-grade larimar can also be set in gold.
  • Quality grading is based on coloration and mineral crystal configuration.
  • Larimar can come in different colors due to the presence of other minerals or oxidation.
  • The blue color of larimar is photosensitive and fades with time if exposed to too much light and heat.
