The Mexican Opals that we sell come from mines in the remote Sierra of Jalisco, Mexico, were Opal mining has been a tradition there since the 1930"s.

To locate & remove these opals from the high silica lava were they are found, & prepare them for mounting in Jewelry, is not an easy process. These Opals are found in areas were there once existed ancient active volcanoes. The grounds were they are found are very hard, and require sometimes that they be blasted with dynamite, to loosen the rock around them. The remaining boulders must be broken apart by hand with a hammer, sledge chisel, and bar. Unfortunately, this results in much lost gem material. Many hands must screen through tons of earth, & rubble, in an effort to find  quality opal material; this involves a lot of work, by many people. After the selected material is gathered, it must be graded, cut, polished, and then stored under observation for several months, in order to insure that the material is "STABLE" and will not crack or craze over. Only after this long and tedious process can this material be safely placed on the market.

About 30 years ago this material was a lot more abundant, and not very well known throughout the world. Many gem enthusiasts, invested in it, and sold it overseas, primarily in Japan and other countries in Asia. The popularity of this gemstone rose dramatically throughout the world in just three decades. Prices rose considerably, due to stronger demand, and increased scarcity. Many of the Mexican Opal mines that once were famous for yielding a constant and rich supply of high quality Mexican opal are no longer producing, and many of the new mines working today rarely meet expectations. These are some of the reasons why this Gem is so RARE, and not commonly seen. Unfortunately, high quality stable material is not easily found,  and this is why it is so treasured by collectors.
