Very rare large kidney stone calcium. For Sale

I know this item is unusual to be selling but this is extremely rare. I had this removed in 2003. It was one of the largest stones removed in the United States. Comprised of very hard calcium it is round, white in color and of course has been sanitized multiple times. Doctors said it took about 20 years to get this size and required four surgeons, and 3 surgeries to remove from my bladder. This would definitely make an extremely good conversation piece as it has been for me. Anyone who collects trance and unusual items should have this in their collection. It weighs just under 3 pounds. Free priority shipping in the US.  Feel free to ask me any questions regarding this very unusual item! Could anyone advise me to a site that buys unusual items for collections. My doctor wanted to keep it badly so I am sure they’re other people who would like it in a collection. If anyone can help me with places that would possibly want it do a display for a collection. Please let me know and I will even pay a finders free to the person that gets me in a serious discussion about purchasing it. Thank you for any help!
