How Is Jasper Formed?
Jasper derives from quartz; the mineral is found throughout the world and is not commonly treated or enhanced when mined. Jasper is a beautiful mineral with captivating color patterns and formations. Although it can be solid in color, jasper is typically spotted, striped or ringed. Each jasper stone possesses a unique pattern or color scheme, making it one of the most unique gemstones.
Jasper is a grainy mineral type. It is known in the scientific community as cryptocrystalline because it consists of very small crystals. The gemstone typically comes in three distinct colors: red; brown and yellow, although it can come in blue as well. Jasper can also come in many different shapes and sizes, from huge chunks to tiny shards.
Jasper has been used by man for thousands of years. Today, the gemstone is commonly found in ornamental jewelry pieces or as a fashion accessory. Although relatively common thanks to the abundance of quartz in the Earth's crust, jasper’s ability to shear off in smooth layers and its unique blend of colors continues to create demand among consumers.
The largest jasper deposits in the world can be found in Russia, the United States (specifically Oregon, California, Arkansas and Texas), India, Egypt, Brazil, Australia, Venezuela and Uruguay.
