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!

In 2003 we procured a small stash of Choyas Geodes from the 1960's in all sizes. We have begun cutting
and polishing some of these now in the winter of 2016-2017and will be listing them as they are finished. It
normally takes better than a week to finish one of these geodes. We will be listing each half individually as
well as offering the matched pair for a savings of around 10%.
This is probably the nicest Las Choyas Geode we have cut in the last 12 years! It is
always a pleasure to find an Amethyst crystal pocket, but it is exciting when we
opened this geode and found a beautiful lavender Amethyst formation over a
botryoidal formation of Chalcedony.with a single dark quartz formation.
This is a rare quality stunning split pair of Las Choyas Coconut geode halves with
beautiful Amethyst crystals and white,blue-grey chalcedony. Amethyst Center
