The mineral collecting world has lost another nice guy, Keith Hayes. So this week, in his memory, any mineral that is linked in some way to Keith. I know that I have purchased a few over the years from KQ Minerals and mineral-auctions.com, such as the diamond from Bingara, New South Wales pictured.
