Hello Michael,
I agree with you. Pieces of Magnetite/Hematite are the most often
offered meteoritewrongs sold to newcomers.
Because I'm a beginner to I've bought even from two IMCA members two
pieces of 'Mekong river iron' as Nantans.
Month later I detected that they were wrongs. Asking for money back
makes them very angry but I won.
The easiest formula for detecting offers of iron wrongs is to estimate
the specific density. Most seller declare length, depth and hight anf
weight of the item.
Calculate now V = (L x D x H x Pi / 6). This is the nearest estimated
volume of an inlet speroid, that means a little more less in volume.
Divide now the given weight by this value and you get a specifiv
density which is hiigher then the original. If this value is less than
7.5 this must be a meteoritewrong if is a big piece ore it is only
shale if it is a small piece.
With this formula I'm "hunting" fake sellers on ebay.
Sincerely Uwe

Thema: [meteorite-list] New Toluca scam on ebay
http://shop.ebay.com/merchant/bandedgila_W0QQ_nkwZQQ_armrsZ1QQ_fromZQQ_mdoZ
Take a look at this guy, selling piles of Magnetite as Toluca
meteorites.
I am concerned because they do resemble meteorites to the lesser
informed and I
have lots of Toluca for sale.
