We present a unique, collectible raw material—1 kg of original, unopened geodes and agates from the iconic Las Choyas site in Mexico (Chihuahua state). The material on offer comes from old collections mined as far back as the 1970s, considered the so-called “golden age” of this site.

An extraordinary thrill and a great adventure when cutting them open
Opening geodes from Las Choyas is an unforgettable experience for every mineral enthusiast. From the outside, all the geodes look nearly identical, but what lies inside remains a complete surprise until the moment you cut them open. This material is characterized by incredible diversity—you may find deep cavities lined with sparkling quartz crystals, beautiful purple amethyst clusters, rare smoky quartz, and multicolored, dense chalcedony bands. Keep in mind that, as with any natural raw material, there are also solid (unveined) specimens, less attractive ones, or those with less crystallization.
Why does the historic Las Choyas mine outperform modern mining operations?
The Las Choyas deposit in Mexico is considered one of the most important sources of geodes in the world. However, there is a fundamental difference between specimens mined several decades ago and those extracted today. Currently, mining operations are conducted at depths exceeding 50 meters underground. To break through such hard layers of volcanic rock, miners commonly use dynamite, which often causes microcracks to form inside the geodes and frequently leads to their damage even before they are extracted. Furthermore, today’s excavated material consists mostly of ordinary, compacted quartz. The material we offer comes from shallow, more diverse sections of the deposit, thanks to which it features a significantly higher proportion of agates and geodes with beautiful, intact crystalline cavities and a healthy, undamaged outer shell.
