Cluster of 3 Beryl or Apatite crystals that have psuedomorphed to Turquoise. This is an excellent example for the locality as most are single crystals (not clusters), crystal size is good with crystals to 1.3cm, and it's in overall good condition (these are brittle on most are destroyed in the removal process). The following is quoted from Mindat: 'Host rock is Teutonia quartz monazite (Beckerman, 1982). Late turquoise replacement of miarolitic cavities resulted in turquoise pseudomorphs after the following minerals: quartz, muscovite, beryl, microcline, apatite as well unconfirmed orthorhombic pseudomorphs labeled as after barite. Chesterman at the Ca. Div. of Mines and Geology confirmed turquoise pseudomorphs after beryl based on morphology, trace beryl remnants and in situ beryl nearby. (Nazelrod, pers. comm.)'.
