Las Choyas Geodes (Mexican Coconut) & Other Geodes from Mexico

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 winters and 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%.

4.9" Polished Las Choyas Geode (Half) Crystal Vug

Sold

This is one of the most unique crystal vug Las Choyas Geodes we have cut in a long time. It is difficult to photograph the unique crystal inclusions under brown chalcedony with a look similar to a shiller-effect that is present in this geode. As an added attraction this geode is fluorescent under SW, MW and LW Ultra-violet light. The orange spot in the fluorescent photo is a calcite crystal in the quartz crystal vug. This geode was cut and matte finish polished in our shop.

This specimen measures 4.9 x 3 x 1.5 inches (12.5 x 7.7 x 3.8cm) and weighs 15.2 ounces, or 0.95 lb (431g)
