How is pink quartz formed?
Although pink quartz has so far only been found in pegmatites, it forms in a hydrothermal environment, at high temperatures, but from a watery solution. It can frequently be found grown on smoky quartz crystals, usually parallel to the underlying smoky crystal. Pink quartz was first found in Brazil in 1959 which is still the main source. There are some reports that indicate that it had been found in pegmatites in the U.S.A. earlier in the 1930s. Specimen seem to come mostly from Minas Gerais, from Linópolis, Galiléia, or Governador, for example. I have once seen an offer for a specimen from Situa da Conquista, Bahia, Brazil, in an ebay auction. Pink quartz that is very similar in appearance to Brazilian specimen can be found in pegmatites in Maine, U.S.A, for example in the Mount Mica Mine in Oxford County.
