Unique gray amethyst heart with green agate eyes

A gray amethyst heart from Brazil with green agate eyes. The mineralogically unusual color combination is particularly striking in the heart shape.

The gray amethyst coloration indicates a special deposit variety with lower iron concentration and embedded microcrystal coatings. This variant is a premium classification compared to typical deep purple standard amethysts.

The green agate eyes are circular concentric microcrystal aggregates with chlorite or glauconite inclusions. Such eye structures form in the first mineralization phase and are later enclosed by the main amethyst phase.

The heart-shaped cut geometry is a curatorial staging decision. The material combination of gray plus green is a distinctly rare color constellation and makes the piece a mineralogical unique specimen.
