caption_attribution_description: English: Kyanite, Quartz Locality: Barra de Salinas district, Barra de Salinas, Coronel Murta, Jequitinhonha valley, Minas Gerais, Southeast Region, Brazil (Locality at mindat.org) This relatively thick crystal with a tiered , complete termination, has INTENSE blue color. It displays nicely with accenting quartz at the base. Although it is rougher than atop, the bottom is also terminated, as it attaches to the quartz. THE COLOR IS THE DEEPEST BLUE I HAVE EVER SEEN IN A KYANITE OF SPECIMEN QUALITY. The price in the gallery may have seemed high for a kyanite, at $375, but when you see it in person, you will definitely agree it is worth it and quite exceptional. Kyanites are usually perceived as rather dull, opaque blades of mottled white and blue, embedded in quartz, and not suitable for the serious collector. However, once in awhile, you get these stunning, transparent-to-translucent crystals, some perched perfectly on matrix of quartz instead of embedded inside of it. 4.6 x 2.8 x 1.3 cm Deutsch: Kyanit, Quarz Fundort: Distrikt Barra de Salinas, Barra de Salinas, Coronel Murta, Jequitinhonha valley, Minas Gerais, Southeast Region, Brasilien (Fundort bei mindat.org)
context_page_description: This list includes those recognised minerals beginning with the letter K. The International Mineralogical Association is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date. This list contains a mixture of mineral names that have been approved since 1959 and those mineral names believed to still refer to valid mineral species.
  The list is divided into groups:
  Introduction •
  A • B • C • D • E • F • G • H • I • J • K • L • M • N • O • P–Q • R • S • T • U–V • W–X • Y–Z
  The data was exported from mindat.org on 29 April 2005; updated up to 'IMA2019'.
  The minerals are sorted by name, followed by the structural group or chemical class, the year of publication, the IMA approval and the Nickel–Strunz code. The first link is to mindat.org, the second link is to webmineral.com, and the third is to the Handbook of Mineralogy.
  Abbreviations:
  ᴰ – discredited.
  Q – questionable/ doubtful.
