mineral specimens of mexicoGemstone and Mineral Information for Mexico

At least 60 varieties of minerals can be found in Mèxico, an estimated 1/5 to 1/3 of all silver that has been mined world wide has come from Mexico. Here is just a sampling of some of the outstanding minerals here in Mèxico: danburite, opal, grossular, rhodochrosite, topaz, adamite (the world's best), fluorite, amethyst, rosasite, smithsonite, goethite, turquoise, calcite, onyx, hematite, pyrite, agate, obsidian, malachite, chrysocolla, to name a few.

Mapimi, Durango - has produces the very best specimens of fluorescent adamite as well as nice specimens of hemimorphite and wulfenite. Adamite is found at other localities around the world but few specimens can compete with the best specimens of Mapimi. The Ojuela Mine is the primary source of Mapimi specimens.

Santa Eulalia, Chihuahua - produces beautiful specimens of creedite, calcite, hemimorphite, smithsonite, rhodochrosite and much more. The Potosi Mine in Santa Eulalia is one of the more productive mines in the area in terms of collector specimens.

Naica, Chihuahua - this Northern Mèxico state provides complex crystals of fluorite, sparkling calcite, brassy pyrite and silver colored galena. Naica fluorites are quickly becoming highly prized specimens, they are perhaps the finest examples of cube/octahedron/dodecahedron combination and the rarer cube/tetrahexahedron fluorite available anywhere.

The state of Sonora on the border with the United States just south of Arizona, is also well know for producing many nice mineral specimens. Copper, copper compounds, silver and silver sulfides are abundant here. Tellurates from the mines of Moctezuma are quite unusual, having provided at least seventeen new tellurate minerals to science as well as specimens of many other tellurium minerals.

mexico gem specimensCharcas, San Luis Potosi - is world reknown for it's Danburite the large clear crystals are easily found on the mineral markets. Topaz is also found here and can be quite nice. A variety of grossular known as "Raspberry Garnet" is found in Coahuila and another garnet gem found in Mexico is andradite which forms iridescent green gemstones. Another green gem is olivine and it is mined in the Chavira peridot-olivine mines in Chihuahua.

Tequisquiapan, Quèretaro and Magdalena, Jalisco offer outstanding opal of many different varieties cultivated in pockets in volcanic rocks such as rhyolites and basalts. The states of Aguascalientes and San Luis Potosi are known for their fire agate, with Calvillo in Aguascalientes producing much sought after multicolored fire agates. Colorful rainbow obsidian and other varieties of obsidian are very abundant throughout Mèxico. Amber found in Chiapas and is similar to the Dominican Republic amber. Both are about the same age (roughly 20 - 30 million years old).

The amethyst localities of Vera Cruz and Guerrero produce some of the most unique amethyst specimens. The Vera Cruz amethysts are often doubly terminated, prismatic, attached to matrix or free floating and clear with a pale lavender color. The Guerrero amethyst is much darker in color, prismatic, phantomed, tapering and majestic. Guerrero amethyst is perhaps the most expensive amethyst in the world by weight.
