The name Amazonite derives from the Amazon River in Brazil and is a mostly opaque green feldspar with irregular color distribution. Deposits are also found in Colorado, India, Kenya, Madagascar, Namibia, and Russia. It is alleged to be the stone the seventh chapter of the Ancient Egyptian Book of the Dead was engraved on and the third stone in the breastplate of Moses. 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.
