Ametrine withamethyst and citrine quartz, also referred to as trystine or bolivianite, as large quantities of ametrine has been mined in Bolivia.

When the first ametrine crystals reached America from Bolivia, a vigorous argument broke out between those who said it was natural and others who said it had to be synthetic or treated. Today botharguments are correct.

The original ametrine crystals are natural and come from quartz veins or stringers in a metamorphic deposit in Bolivia. But we have also figured out how to produce ametrine through heat treatment, which means we can copy nature.

It is safe to say that ametrine is a unique form of quartz wherein two gem colors occur in the same crystal. this has given the gem industry and artists an entirely new treasure to carve, facet and use to create stunning jewelry and gem carvings.

The introduction of ametrine into the modern gem market came as a surprise, though this unique Bolivian gem deposit had been known to the native peoples in the area for several hundred years. the problem is the area where the deposit is located is one of the most remote parts of Bolivia.
