Fluorite on Quartz Matrix Elmwood Mine, Carthage, Tennessee
"Buy minerals when they look common as dirt" Fender Family Maxim
Here is a case in point. At one time in the late 70's throughout the 80's Elmwood was producing spectacular mineral specimens in large quantities. The market became flooded and the effete started declaring them as common and not that important and why would you want one.
The Elmwood mine management cleverly and fairly allowed their miners collecting time. In order that everyone would achieve the same market price the management would gather the minerals from the miners and auction them off in lots. Collectors became so bored with Elmwood that at some auctions only 2 dealers showed up - Chris Wright (Hot Springs, Arkansas) and Collector's Choice (Houston, Texas now closed). Now these specimens command a premium. You could have bought an Elmwood calcite for $20 25 years ago and now in some quarters that same specimen could reach into the thousands.
Buy minerals when they look common as dirt.
Currently you should be considering Mexican creedite, African Shattuckite and Russian Uvarovite.
