The Anahi Mine lies in a heavily-forested area of plains and rolling hills in the tropical lowlands of far eastern Bolivia, close to the border of Brazil. It is located in Germán Busch province, near the La Gaiba and Mandioré lagoons, in the municipality of Puerto Quijarro, Santa Cruz. (Some mineral descriptions for the Anahi Mine state it is in the high Andes, but that is not true.)
The mine exploits quartz veins in dolomitic limestone. Its products include amethyst (on average, 44% of production by weight), ametrine (33% of production) and citrine (23% of production), along with colorless or milky quartz of little or no value and not quantified above. Most of the mining occurs underground, although some strip pits have been opened.
The Anahí mine is a legend of international intrigue and mystery. In the 17th century, Europeans were first introduced to ametrine, when a Spanish conquistador presented samples to his monarch. The conquistador had received the ametrine mine as a dowry when he married a native princess named Anahí, from the Ayorea tribe. The deposit was exploited sporadically by Indians from the Ayorea tribe, who sold their production at a missionary post to precious stone merchants from Puerto Suárez. In the late 1970s, active exploitation began, when the demand for gem-cutting material drove Brazilian, Bolivian, and Paraguayan gem traders into the area. In 1989, changes to the Bolivian constitution and internal code legalized mining in fiscal reserves. A Bolivian company, Minerales y Metales del Oriente S.R.L., acquired the concessions, which officially named the Anahí mine in honour of the Ayorean princess. In addition, he restructured the mining and trade of ametrine.
These alleged legends of a "Princess Anahí", involving a romance between a "princess" of the Ayorea tribe and a Spanish conquistador named Don Felipe are recent inventions from gem marketing literature and have no historical basis.

Detailed Mineral List:
| ⓘ Quartz Formula: SiO2 Description: The "citrine" colored portions of ametrine are colored by inclusions of iron oxides/hydroxides, hence it is different from other natural citrine. Some authors would not call it citrine in the strict sense. However, it is correct to say that the mine produces citrine, as this is the name of the gem material "citrine".
