huge, particularly beautifully formed rock crystal cluster from Minas Gerais, Brazil

A huge rock crystal cluster from Brazil, Minas Gerais. Numerous quartz points grown together from a common growth substrate to form a mineralogically exceptional cluster aggregate.

Rock crystal clusters form when several individual crystals grow from a common mineralization surface and combine into a dense aggregate in their final form. The aesthetic growth geometry is a site-specific collector's characteristic.

The Brazilian deposits in Minas Gerais are known worldwide for high-quality rock crystal mineralizations. The state has been one of the classic quartz provenances since the 19th century.

A cluster of this size documents an exceptionally extensive constellation. The material value increases disproportionately with the cluster size and the clarity of the individual points.

A Brazilian museum-worthy collector's item with documented Minas Gerais provenance and gallery-quality dimensions.
