Visual description

Two long, near-mirrored triangular wings, their cavities lined edge to edge with amethyst points. Color runs from deep grape — almost black at the darkest tips — out to soft lavender at the rims, where a blue-grey agate band traces each wing like a drawn outline. A mass of white quartz sits at each wing tip, two bright counterpoints. Up close, thousands of crystal faces scatter light like crushed diamond over the deep purple ground.

A "butterfly" is the rarest way to present an amethyst geode: one cavity, sawn into two halves, opened outward like wings — every ridge on the left answered by its mirror on the right, because both grew as one. This pair spans nearly a meter, a symmetry the earth composed and a saw merely revealed.

Why collectors want this

Room-scale mineral pieces are usually about mass; this one is about symmetry. A natural mirror image at 94 centimeters is a statement few interiors can ignore — and unlike a single geode, a pair composes a wall, an entry, an axis.

Living with it

Give the pair a wall of its own and light each wing from its outer side, crossing toward the center — the gradient from lavender rim to deep-purple heart doubles in effect when both wings glow at once. Sited against a pale wall, the agate outline reads from across the room.
