Natural Ametrine Crystal Geode – 400g

A truly rare and extraordinary specimen — this natural ametrine crystal geode weighs 400 grams and showcases one of the mineral world's most unusual and beautiful phenomena. Ametrine is a naturally occurring variety of quartz that displays both amethyst purple and citrine yellow within the same crystal, the result of differing oxidation states of iron in different zones of the stone during its formation.

In geode form, this dual colouration creates a breathtaking interior — a cavity lined with crystals that transition between rich violet and warm golden yellow, sometimes within a single point. Each ametrine geode is entirely unique, as the distribution of colour is determined by the precise conditions present during millions of years of crystal growth.

Ametrine is found in only a handful of locations worldwide, making this a genuinely rare collector's piece as well as a visually spectacular one.
