Ametrine is a natural blend of amethyst and citrine in one crystal, whose bicoloration results from a temperature variation during crystallization. Under certain precise geological conditions, zones of the same crystal form at slightly different temperatures, creating distinct oxidation environments for the iron ions responsible for the colour. The purple comes from iron in an oxidising environment, the yellow from iron in a reducing environment — the same impurity, two different conditions, two opposing colours in a single crystal. Almost all the world's ametrine comes from a single deposit: the Anahí mine in Bolivia. Each JUMBO piece is an impossible meeting made real, a reconciled duality the earth offers in only one place in the world.
 
Emotional and spiritual virtues — It is associated with balance between opposites, clarity of action and the unification of inner dimensions. It accompanies those living in tension between two parts of themselves — the intuitive and spiritual, and the pragmatic and concrete. Its vibration, both high and grounding, invites one to stop choosing between head and heart, between dream and action. Amethyst works on intuitive clarity and connection to subtle planes; citrine works on confidence and the ability to manifest concretely. Together, they form a stone of total coherence — for those seeking to be whole rather than divided.
 
Legend — The Anahí mine in Bolivia is named after a legendary Guaraní princess. According to tradition, a Spanish conquistador married Princess Anahí and received this bicolour stone mine as a dowry; on his death he gave these stones to his family in Spain as a symbol of the union between two worlds. This legend of reconciling opposites seems woven into the stone itself — purple and yellow, spiritual and earthly, united in a single crystal.
 
JUMBO orders require time for crafting, ranging from 2 to 3 weeks during the busiest periods. The photo is not contractual — each stone is unique, and its imperfections are the testimony of a natural stone.
