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.

  • A piece of brecciated matrix with two levels of grossular crystals. The crystals are, for the most part, a light green with one patch that is tinted a more substantial green. As well there are a number of prisms of a darker mineral, presumably epidote, on the lower level. Displays well!

  • There are two fronts to this specimen! One side is totally composed of very light green, acicular diopside crystals. The other side features absolutely colourless grossular crystals. The grossulars sparkle like ice crystals and have absolutely no colour -crystal clear with dodecahedral habit. Nicely mounted on an acrylic base which can be easily removed. Displays very well.
Grossular, PectoliteJeffrey Mine, Asbestos, Quebec, Grossular

  • $250.00
  • Jeffrey Mine
  • Asbestos
    Quebec, Canada
  • This is a rather large plate specimen with the entire front/top speckled with beautiful, gemmy, orangey-cinnamon grossular crystals. The grossulars are the classic Jeffrey mine trapzohedra-dodecahedra combination form of crystals. The pectolite crystals are elongated, heavily striated colourless crystals typical of the Jeffrey Mine. All of the grossular crystals and pectolite crystals lay on a bet of non-descript, rounded aggregates of chlorite. Great looking specimen that sparkles with grossulars!
