Pearls come in many colors, usually depending on mollusk and water that it grew in, and are usually found in oysters. They are built up mother-of-pearl (calcium carbonate) and though the beads used in jewelry are typically small, they are extraordinarily compact which makes it very hard to crush them.
Named after the Labrador peninsula in Canada where it was originally found, Labradorite’s bright flashes of color are a result of schiller, or labradorescence. In the 1940s a similar material was found in Finland that exhibited the entire color spectrum, this was nicknamed Spectrolite. Larvikite is a silvery gray Labradorite from Scandinavia. Other deposits are found in Australia, Madagascar, Mexico, Russia and the United States. Labradorite is a stone of magic and protection.
