caption_attribution_description: English: Dioptase Locality: Tsumeb, Otjikoto (Oshikoto) Region, Namibia (Locality at mindat.org) With the great Tsumeb mine now history, specimens of this quality are hard to come by. These deep, emerald green dioptase crystals, to a whopping 2 cm in length on the largest, completely cover the whole specimen with glistening color. In addition, they are fairly gemmy for the species and have vibrant luster. Just a great piece! NO DAMAGE to the display face. Lastly, the piece photos better horizontally but really can be stood vertically for maximal display, with the larger crystal then centered on the top half of the specimen.5.2 x 3.4 x 1.4 cm Deutsch: Dioptas Fundort: Tsumeb, Otjikoto Region, Namibia (Fundort bei mindat.org)
context_page_description: This list includes those recognised minerals beginning with the letter D. 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.
