This auction is for a 3lb chunk of Kona Dolomite. It is 6 x 3 x 7 Look at the photo. This was collected in the 70's. I resently purchased a rock shop that has been closed for many many years. This rock shop was in business in the 60's 70's and early 80's. All sales are final. AS ALWAYS, MY AUCTIONS START AT A BUCK! (to keep in the true spirit of an auction) Buyer pays $8.10. I will use a flat rate shipping box. I do combine shipping for multiple wins. I do try and explain items as they are, and pack carefully. I have had many questions, as they are asked I will post the question as I get them during the auction. Most all items are one of a kind and from the old rock shop. Email with any questions. Good luck and happy bidding!!!
