Included quartz

  
A very interesting and to my knowledge unique specimen featuring a fanspray of elongated pink crystals inside a quartz point. The crystals inside have been shown to be montmorillonite but the form is wrong because the mineral usually is amorphous from the locality, indicating they are a pseudomorph replacement after another, as yet-unidentified mineral species. From Tim Sherburn, who got it from dealer Mark Rodgers in 1984. Note that the front has been polished to enhance display of the inclusion.
