Amethyst rectangular crystal face — Brazil, 148 g

Description

This amethyst presents a rectangular crystal face densely covered with purple crystal points; the front surfaces are sparkly and highly reflective. The specimen retains a rough, natural outer border, and the lower edge is uneven with a small open notch. Measuring 5.5 × 4.5 × 5 cm and weighing 148 g, the piece is a compact example of crystalline quartz from Brazil. The densely packed points on the face catch and reflect light across the surface, while the untrimmed outer edge preserves a more natural, textured appearance. Amethyst is the purple variety of quartz (SiO2), and Brazilian material is commonly encountered in collector specimens and decorative pieces. This description focuses on the specimen’s visible form, colour and surface character.
