Amegreen

I. The Metaphysical Reading

How the stone has been held.

Held as a stone of heart-mind reconciliation - the green heart-sector paired with the violet crown-sector in one continuous crystal. Practitioners reach for amegreen when devotion and clarity are pulling in different directions and a single, integrated presence is needed.

II. The Scientific Reading

What the lattice actually does.

Amegreen is the rarer cousin of ametrine, formed in the same Anahí deposit where twinned amethyst and citrine crystallise across a shared Brazil-law twin plane. In amegreen, the yellow sector is instead the green prasiolite variety - a colour produced by Fe²⁺ centres in a reducing environment. The two colour sectors reflect abrupt changes in oxidation state during growth rather than mechanical mixing.
