Quartz from
Anahi Mine (Anay Mine; Anai Mine), La Gaiba mining district, Ángel Sandoval Province, Santa Cruz, Bolivia

Locality type:Mine
Classification
Species:Quartz
Formula:SiO2
Comments: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".

Confirmation
Validity:Believed Valid
