Amethyst druse (cut base) — Brazil, 207 g

Description

This polished Amethyst druse presents a rounded arched top and a flat-cut base, with a densely drusy surface and clear colour zoning from a deep purple centre to paler lilac at the edges. The druse is intact to the exposed crystal surface. Measuring 8 × 4 × 5 cm and weighing 207 g, the piece is a compact, palm-sized specimen that sits flat thanks to its cut base. Amethyst is the purple variety of quartz (SiO2); quartz commonly forms crystals in cavities and drusy linings, which is the habit exhibited here. The specimen’s confirmed origin is Brazil.
