This is a section of a colorful Precambrian rock material green Mica (muscovite) from Eastern Ontario Area and an excellent example of Grenville metamorphism. The name is derived from the Greek word that means to split.
The Grenville Orogen is a deeply eroded and highly uplifted orogenic belt that extends from Labrador in northeastern Canada to the Adirondack Mountains and southwestward under the coastal plain of the eastern United States. It developed from about 1.5 to 1 billion years ago.
Schist is faliated medium grade metamorphic rock. It formed by metamorphosis of mudstone and shale or some form of igneous rock. It usually has better crystallization of mica minerals. This is called schistosity texture. There are many types of this rock so they may be named for mineral comprising the actual rock for example Mica schist.

You will receive 1 Garnet crystal selected at random. Each Garnet crystal is beautiful and unique, variations in size and shape should be expected.
These nicely colored Garnets are from Ontario, Canada. Garnets as a group are relatively common in highly metamorphosed rocks and in some igneous formations. They form under the high temperatures and/or pressures that those types of rocks must endure. Garnets can be used by geologists as a gauge of how much temperature and pressure the rock has endured.
Garnets do possess high indices of refraction, are hard enough, have pretty colors, are wonderfully transparent, lack cleavage and are durable; thus making good candidates for gemstones. They are greatly variable in colors and varieties, and many of these are both rare and beautiful, producing genuinely precious gemstones. Some garnets are truly unique in the mineral kingdom and have much to offer as both gemstones and mineral specimens.
Garnet has been dubbed the gem of faith, constancy and truth. Asiatic tribes carved garnets into bullets in the belief that their fiery color would inflict more deadly wounds. They were ground into powder for the treatment of fever or jaundice. If the cure didn't work, the apothecary was accused of using an imitation.
