Pietersite is a unique gemstone known for its striking colors and swirling patterns. It is primarily composed of quartz and is often found in shades of blue, gold, and brown. This stone is formed from the alteration of jasper and agate, making it a type of chalcedony. Discovered in Namibia in the 1960s, Pietersite is sometimes referred to as "tempest stone" due to its dynamic appearance. It is popular in jewelry and is believed by some to have metaphysical properties, promoting emotional healing and clarity.
