3.1" Las Choyas Geode With Clear Quartz

This is a beautiful, cracked "coconut geode" from Las Choyas Mexico. It contains a pocket of quartz/amethyst crystals. This piece has 3 pieces to it, after removing the small end section you can look inside to see the geode full of crystals, then you can continue to open the geode in half to see all the clear quartz.

Geodes are rounded, hollow voids in rocks filled with crystals and other minerals. They are typically formed when air bubbles inside of volcanic rock form hollow cavities. Over time, as mineral-rich water seeps into the rock it beings to deposit tiny crystals on the sides the hollow cavity. After millions of years, the flow of water gradually builds crystals inside the empty space.

Las Choyas geodes, often referred to as coconut geodes are mined from 100 to 200 feet below the surface near Chihuahua, Mexico. Shafts are drilled down to the geode bearing white clay, and then tunnels are dug horizontally to extract the geodes.

The geodes typically range from about 2-6 inches in diameter and can contain a variety of minerals and crystals. Most hollow geodes contain a variety of quartz ranging from clear quartz to smoky quartz to more rarely amethyst. Many secondary minerals such a goethite, hematite, mordenite, calcite and galena may also be present in some geodes.
