Amethyst cluster — Brazil, 844 g

Description

This is an Amethyst cluster of multiple crystal points showing a range of pale to medium purple tones. The cluster presents as an assemblage of standing points rather than a single large crystal, with visible variation in colour between individual crystals. The piece measures 11 × 9 × 8 cm (H × W × D) and weighs 844 g. Amethyst is the purple variety of quartz (SiO2). Quartz commonly forms crystals in cavities, veins and geodes, and Brazilian material is frequently encountered on the market as clusters and points.
