Mineral Fakes What to look for & What to do when you find one
What constitutes a Mineral Fake? The specimen is not the handiwork of Mother Nature The crystals did not grow naturally The crystals were glued into place The crystals were dyed, irradiated, coated, etc. I personally believe that modern specimens matched up with old labels are fakes too.
Why would someone make a fake specimen? Enhance the perceived value of a rock A way to use nice crystals and pass them off as exceptional specimens A way to essentially steal from unsuspecting buyers Personal reasons…
Some distinctions need to be made Repaired specimens are not fakes Restored specimens are not fakes As long as the Repair and/or restoration replicate the original specimen. As long as that information is noted on the specimen label
How do you know youve been had? This thing looks perfect! Man, I am going to buy it! Wow! What a great deal I got! I cant wait to get a better look at this when I get home under my microscope! Ah Crap!
The first thing to realize is that we all buy and likely have bogus minerals in our collections. The best dealers in the world have a drawer full of them, including me, and all museums have them too. They are EVERYWHERE!
Your Most Valuable Tools for Fake Specimen Indentification Handlens A Microscope A UV light source Experience
This specimen was cast and then soldered to some other gold bearing matrix. An atomic absorption test proved that the alloy was copper and silver with gold while the other visible gold was void of any copper.
Ok – so now you have found your mineral fake. Whats next? Contact the dealer and let them know. Be nice about it and keep in mind that most dealers were likely been duped before you. Every dealer worth his or her salt will gladly refund you your original purchase price. If there is a dispute go to a non-partisan 3 rd party to get a 2 nd opinion. The vast majority of the dealers out there are honorable people and will stand by their name.
