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,
malachite, chrysocolla, to name a few.
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.
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.
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
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.
