Calcite on amethyst - Brazil | Ref541

Specimen description

This calcite on amethyst association from Minas Gerais, Brazil, was collected in 2008. The specimen is displayed horizontally on an acrylic stand.

The amethyst forms a crystallised base composed of numerous closely spaced purple points. Above it, the calcite develops as several pale crystals, including two main upright crystals that diverge slightly from one another.

Smaller crystals occupy the intermediate area and partially cover the calcite. The larger crystals display irregular surfaces with fine crystallisation, while the amethyst remains clearly visible across the entire lower section of the specimen.
