Item Description
A warmly colored specimen of Opal from the San Juan del Río Municipality in Queretaro, Mexico featuring slightly translucent reddish colored patches of what on the label is referred to as "Paste Opal" (a term I'm not familiar with) sitting on matrix. There are some interesting "channel"-like grooves in the piece, giving the impression that it might have formed a "cast" after a preexisting mineral. With backlight, there is a bit of translucency that can be seen in certain areas. Not your typical Opal for this district, and certainly a cool specimen for any fan of worldwide Opals. 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.
