Mimetite (ex Al Kidwell Collection)

Item Description

Typically the Mimetites from the San Eulalia are classics, and this piece dates back probably to the 1970s when some of the better specimens were coming out of this storied locality. This piece is filled with well-formed, narrow hexagonal prisms of Mimetite measuring up to 3 mm sitting on oxidized matrix. The color ranges from a milk chocolate brown hue on the top to a gorgeous yellow color underneath. The crystals on the underside of the piece are rather lustrous and gemmy and looks great with magnification. Excellent condition all over, I can't find any major damage anywhere. From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974.
