Albite : Na[AlSi3O8] | |

Magnet Cove, Hot Spring Co., Arkansas, USA 10.4 x 7.3 x 4.2 cm. Though this area is known for minerals widely, it is not particularly known for albite specimens. So this is actually quite an unusual specimen and comes from a recent find by Donald Heins at this old locality. These sharp crystals have formed knobs or rosettes that give the specimen pretty 3-dimensionality. |

Mo-Ti Corporation prospect (The Pyrite deposits), Magnet Cove, Hot Spring Co., Arkansas, USA In August Justin, Louise (Justin's Mom), & I went to Hot Springs to visit Chris Wright (Wright's Rock Shop). Chris showed us awesome hospitality and gave us the inside scoop as to which part of the creek was the best. This was the ONLY anatase that any of the 3 of us found.
