7.9" Smoky, Yellow Quartz Crystal (Heat Treated) - Madagascar

Madagascar produces some beautiful quartz crystal specimens, some of which come from the Ambolo quartz mine in Antsirabe. Smoky quartz and citrine quartz have also been collected from this area, however the supply of natural citrine is extremely limited.

This specimen has the trademark yellow "citrine" coloration although it is not natural. It acquired its color through heat treatment of smoky quartz. The yellow "citrine" quartz coming out of Madagascar is heat treated, even though it's being listed by dealers as "natural". Natural citrine is quite rare and the cost will typically reflect this. If the price of a quartz specimen that's listed as natural seems too good to be true, it likely is.
