Jeffrey Mine, Asbestos, Quebec, Grossular

The Jeffrey Mine is one of the most famous localities for Grossulr garnet in the world. The mine has been closed for a number of years now and although some vesuvianite has been produced in the last few years by salvagers, nice grossulars like these are only available from old collection or caches. All are gemmy and unique!
