Jerry Rosenthal had twelve full display cases of exceptional minerals. Below is his introduction, as stated in one of his exhibits:
I grew up in the orchard country of San Jose that is now Silicon Valley. During my early years my interest was sparked by my grandfather who gave me a petrified wood domed limb cast. I was intrigued by the thought of wood turning into stone.
My collecting began in thw 1980s once I had some disposable income. I had a deep fascination with lapidary tools and what you could do to rocks with them. As I continued on my interest branched into actual mineral specimens. I met lots of dealers, diggers, collectors, prospectors, traders and more than a couple of con men. Thanks to finding a few honest dealers I was able to compile a collection of over 800 specimens of which a fraction are presented here.
For years my collection was "housed" in cardboard flats and boxes. With the expansion of my plumbing business I was able to build a custom walk in display room to show my mineral and sphere collection. The beauty of the minerals is why I collect but I should also mention that I am color blind so don't be surprised if I ask you what color my minerals are.
Pictured below are all of Jerry's public showcases, as well as some individual minerals from within those cases.
