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!

  • This vuggy matrix has several openings lined with creamy-whitish crystals of grossular. There are also lots of tiny lavender, micro vesuvianite crystals on the grossular crystals. The matrix is interesting in that it seems to be composed of white grossular laced with laths of both grren and lavender vesuvianite streaking through it. Interesting and different type of crystallization from the now closed Jeffrey Mine. Displays very well.
