Though small, this specimen warrants some close examination. It basically consists of a flat shard of a broken quartz crystal into which are partially embedded 2 green Elbaite crystals, along with the shards of a broken Elbaite. The larger crystal has dimensions of 0.9 x 0.5 x 0.4" (2.3 x 1.3 x 1.0 cm) and the smaller crystal measures 0.4 x 0.3 x 0.2" (1.1 x 0.7 x 0.5 cm). Both are in pristine condition, showing no damage whatsoever, and have excellent trigonal prismatic form. The larger crystal's shallow pyramidal termination is naturally disjointed due to the crystal's almost fibrous and compact nature, whereas the smaller crystal's termination is enveloped by the quartz, and so cannot effectively be studied. Their almost fibrous appearance also makes their lusters appear silky instead of vitreous, except on their terminations. They have a forest-green color that has an olive-green tinge, and show some translucence/dim transparence along their prism edges. I believe that when cut, such material produces "cat's eye" stones. The quartz host consists of a portion of a crystal that broke off and underwent noticeable healing. Portions of one prism face and two termination faces are visible. The quartz is colorless, transparent and rather clear, though it does contain many visible cloudy inclusions.
