Ametrine

Ametrine is quartz variety. Distinct purple and yellow zones make each piece visually individual. This page separates mineral facts from retail terminology and traditional crystal symbolism so you can compare pieces more confidently.

What Ametrine is

Ametrine combines amethyst and citrine colour zones within a single quartz crystal due to different oxidation states of iron during growth. Its listed Mohs hardness is 7, and its crystal system or structural category is Trigonal. The chemical composition is commonly written as SiO₂.

What to look for when buying

Natural ametrine is strongly associated with the Anahí mine area in Bolivia; extremely sharp colour splits are possible but provenance helps. Treatments are not automatically a problem, but they should be disclosed. For ametrine, common treatment or enhancement notes include: Heat treatment can alter quartz colour; synthetic and treated bicolour quartz exists.

Care and display

Water: Generally tolerant of brief water contact. Light: Avoid prolonged intense sunlight.

Traditional associations

In modern crystal traditions, ametrine is often associated with balance, clarity, confidence. These are cultural or spiritual associations rather than scientifically demonstrated effects. A crystal should not be used as a substitute for medical, mental-health, financial or other professional advice.

Where it works visually

Common display ideas include desk, living room. Placement should also account for hardness, cleavage, sunlight, humidity, pets, children and how easy the specimen is to knock over.

Common sources

Material sold under this name is commonly sourced from or associated with Bolivia. A country name on a listing is not the same as mine-level provenance; individual specimens should keep their own supplier and locality records whenever possible.
