Full Answer

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.
