Description
Amethyst with Pyrite Overgrowth – Jacuí, Soledade, Brazil – 3361 grams
A rare combination from a historical site
This exceptional mineral from Jacuí, Soledade in Brazil, displays a fascinating combination of amethyst and pyrite overgrowth. During a later mineralization phase, the original amethyst crystals became covered with a fine layer of pyrite, creating a brilliantly shimmering surface that immediately catches the eye.
With its dimensions of 18 x 18 x 7 cm and a weight of 3,361 grams, this is an impressive collector's item that will appeal to both mineral enthusiasts and collectors of rare specimens.
Originating from Jacuí, Soledade
Jacuí, located near Soledade in the Brazilian state of Rio Grande do Sul, has produced some remarkable combinations of amethyst and pyrite in the past. The mine from which this material originated was closed around 1985. As a result, new finds have become extremely rare, and nowadays such pieces appear mainly from old collections or former stock batches.
That makes specimens like this increasingly difficult to obtain and particularly interesting for collectors.
A magnificent crystal landscape
The surface of this specimen consists of countless crystals completely covered with a fine pyrite overgrowth. This creates an almost velvety sheen that transforms into thousands of sparkling reflections under the light.
Along the edges and between the crystal groups, beautiful zones of light purple amethyst are still visible, creating a wonderful contrast between the soft color of the amethyst and the metallic luster of the pyrite.
A geological masterpiece
This specimen shows how various mineralization processes have followed one another over millions of years. First, the amethyst crystals formed, after which pyrite deposited over the surface and created an entirely new appearance.
The result is a mineral that is not only aesthetically pleasing but also tells a remarkable geological story.
An exclusive collector's item
Due to the combination of origin, rarity, and spectacular crystal formation, this specimen is one of the more exceptional pieces from Brazil. It is an excellent object for a high-quality mineral collection and also forms an impressive natural eye-catcher in a home or display cabinet.
