Beautiful phantom amethyst point from Brazil

A phantom amethyst point from Brazil. Narrow columnar geometry with good vertical height, with phantom layers visible as geometric linear patterns inside.

The phantom layers document the growth history of the crystal. The more phantom lines are visible, the more eventful the geological past of the solution chemistry. Some pieces show only a single layer, others several on top of each other.

Brazilian phantom amethysts from Rio Grande do Sul have been documented as collector's items for decades. The deposits in the Serra Geral basalt formation are the primary source for such material worldwide.

The slender columnar geometry makes the piece a vertical display. With backlighting, the phantom interiors become particularly legible.
