Quartz crystal points, large in size with B grade quality, the crystals show the termination of a quartz crystal as expected, however due to the lower quality of these specimens, they are not as transparent or of 'text book' qulaity as our other samples. These specimens are ideally suited for educaitonal use where multiple specimens may be required for a class to observe. They are large and so easy to observe, approximately 10 to 15 cm in length. Quartz is one of the most common minerals found on the surface of earth, a silica mineral and is found as a common constituent in many rocks. It has many other variations depending on chemistry of colour such as amethyst, citrine, jasper, aget and more.
