These specimens of orange-colored baryte are a classic of the mineralogy of the La Unión-Cartagena area. This piece stands out for the intense brightness and a marked color zoning, which shows banded zoning on the tabular crystals, those form aesthetic rosettes. Very elegant specimen.

On a thin limonite matrix we can enjoy two aggregates and aesthetic baryte rosettes formed by lenticular crystals are arranged. Both aggregates are complete, but one of them shows an unusual perfection. It comes from a mine known for its ocher tone barytes,but this shape is not very common in this mine.

Main crystal: 23 x 20 mm. (roseta)
