Quartz    Tafelkop, Gobabisbert Mountains, Namibia.   Ex. Harold L. Dibble collection and shown as a figure in his book, “Quartz”.  This small clear crystal is a fine example of a reverse scepter, which is why Harold chose to include it in his popular book.  The piece measures 4.7 x 4.2 x 3.5 cm and the main crystal is 3 cm.  It is damage free and a textbook specimen (literally).  $150
