Carborundum is also known as Silicon carbide (SiC), a chemical compound that can only be found in nature in the form of the extradorinarily rare mineral known as moissanite, which is found only in trace amounts in certain meteorites, as well as corundum deposits and kimberlite. As such, practically all caborundum in the world is a man-made synthetic. It was originally used starting in 1893 as an abrasive, and later in car brakes, car clutches, and parts of bullet-proof vests. It also has electronic applications, as it is used in LEDs. Synthetic carborundum is also used in jewelry
This particular specimen is itself synthetic as well, bearing a purely decorative function, although it remains a stunning example of human ingenuity and the wonders of scientific innovation applied to geology. Each specimen is totally unique in shape and size (though the sizes are all similar), but all are covered in an incredible array of sparkling colors, primarily blues, greens, and purples of varying shade. It essentially appears to be an iridescent hunk of coal, really unlike any rock or mineral you’ve ever seen. Makes a great piece of decoration for any desk or room, and an interesting conversation-starter for the classroom.
Note: This specimen often has sharp edges - keep away from young children, and be careful not to cut yourself or splinter the mineral
