Just came across some of the gold I found detecting on the west coast of Tasmania many years ago . I melted down a fair few of the small nuggets I found to make my wife's and my engagement and wedding rings. Biggest piece only 2 cm across. Hard work that metal detecting ,but I guess you only have to swing over the right piece to strike it rich.; Keith Lancaster - Minerals and Gemstones of Tasmania and their locations.
