Larimar

Larimar (also lorimar) is a rare blue variety of pectolite found only in the carribean sea. Its colourations vary from white, light-blue, green-blue to deep blue. The deep blue variant is known as volcanic blue.Larimar jewelry is available on practically every street corner and beach in the Dominican Republic, and elsewhere in the Carribean. Most jewellery produced is set in silver, but high grade stones are often set in gold.Quality grading is according to coloration: white is low quality, volcanic blue high quality. Most cheap jewellery ranges between white and light-blue.
High quality jewellery utilizes stones between sky-blue and volcanic blue, often in combinations of both. Greenish colorations are also known but not well regarded, unless the green is intense. It should be noted that pectolites are photosensitive, which causes the larimar to lose its blue colouration over the years.
