Las Choyas Geodes

Las Choyas geodes are also known as Coconut Geodes. They are mined in Chihuahua, Mexico. The geode
pockets are usually located at least 100 feet below the earth’s surface. The geode sizes range from 2 to 6
inches in diameter. These geodes can be hollow, semi-hollow or may also be filled solid with quartz and
agate. (Solid ones are referred to as Nodules) The hollow geodes may have many different types of crystals
inside such as Clear Quartz, Smokey Quartz, and if you are lucky, some amethyst. There may be secondary
minerals or formations such as goethite, hematite, mordenite, calcite, apatite, stalactites, galena crystals to
name a few. Las Choyas Geodes are amazing works of mother earth’s art!
