This is a good example of a Hessonite Garnet, from the Jeffrey mine in Quebec. Small size garnets lead up to a single larger one at the top of the cluster. The larger one measures about 1 x 1 cm.  It comes on a 1 1/4" black acrylic base. The Jeffrey mine has been closed to collecting for many years, as I've heard NASA has leased it to mine asbestos for use in their heat shields. Specimens have become more and more scarce.
