Quartz "Pineapple" growth (ex Kay Robertson Collection)

Item Description

A really cool and unsual Quartz specimen from Mexico in the form of what was originally called a "pineapple", but I've seen similar specimens from other world localities referred to as resembling a "cactus". With that said, the piece features sharp, well-formed, rather lustrous, striated hexagonal prisms in a somewhat layered growth around the main crystal in the center. The label states that the piece is from near Alamos, with no more specific locality information. If you collect worldwide Quartz crystals or minerals of Mexico, don't miss out on this beautiful and odd specimen! Valued at $800. Ex Kay Robertson Collection (#2756). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).
