Formation & geological history
Formed in cavities in basaltic rocks associated with volcanic activity. Only found in the Dominican Republic.
Uses & applications
Primarily used as a gemstone in jewelry due to its striking blue color and patterns.
Geological facts
Larimar was discovered in 1916 but was not commercialized until 1974. Its name is a combination of 'Larissa' (the daughter of the man who rediscovered it) and 'mar' (Spanish for sea).
Field identification & locations
Identify by its unique sky-blue color with white marbling, found exclusively in the Dominican Republic. It is relatively soft, so care should be taken to avoid scratching.
