Pearl.<\/p>\n<p>A gem is a precious or semi-precious stone that is used in jewelry. Some common gems include diamonds, rubies, sapphires, and emeralds. Pearls are not considered to be gems because they are not formed from minerals. They are formed when an irritant, such as a grain of sand, enters an oyster and the oyster secretes a substance called nacre to coat the irritant. Over time, the nacre builds up and forms a pearl.<\/p>\n<p>Cat&#8217;s-eye is a type of quartz that has a chatoyancy, or a band of light that appears to move when the stone is moved.
