The Harold L. Dibble Collection

Harold Dibble, is the author of "Quartz: An Introduction to Crystalline Quartz", and was a well known east coast collector.  He passed in 2014 and his collection of fine minerals will be offered in upcoming months.  Some of his most important specimens grace the displays in the Seaman's and Smithsonian museums.  Harold's passions also included art and he was early in recognizing minerals as Nature's works of art.  Many of his minerals reflect this ideal.
