TESTED ICP AND XRF This piece has been tested by a certified lab using an Bruker M1 Mistral Micro XRF Spectrometer.
It's been tested multiple times. It's VERY Rare.  Origins Peloponnese Greece Raw material ore.  Free returns if not satisfied. Weight is 426 Grams. 
It has around 17+ grams (rough estimate) of Rhodium. Palladium is over 25+ grams . Silver content is over 30+  grams.
This is worth much more then I'm selling it for but because of the disbelief due to its extreme rarity its almost free compared to an sale price it will bring one day in the future. This is very rare extremely even. The reason for its existence is due to the area. There is many reasons its real. If serious and interested in learning  more about this piece feel free to message me. Please don't message me with disbelief to begin with though I'd appreciate it. Also I'm looking for partners to fund a commercial operation of extracting more of similar pieces like this with serious interest to be made no major high end corporations are presently here extracting anything from the ground here besides two very big water bottling companies including pelogrino water company that slaps their name on it, keep in mind its Greek water. 
The area is sitting on prehistoric hydrothermal pockets.  Thanks for your time.
