It weighs approximately 4 lbs 2 oz and measures approximately at its largest points 10" wide 5" tall x 1" thick. This gem as well as many others that we have for sale, were collected by someone in the 1960's and 70's. He bought rough agates direct from Brazil, Uruguay and other South American countries by the truck load. He had a large warehouse full of lapidary saws and polishers. Some stones the polish could be better and there maybe some saw marks and possibly need reworked. Please see all of the pictures as this is a good representation of the description of the stone. If you would like multiple stones please message me before purchase to combine.
