Amethyst triangular wedge, Brazil — 100 g

Description

This triangular amethyst wedge shows one face densely coated in a sparkling purple crystal druse while the opposite side and back remain a rough grey‑green surface. The piece narrows to a pointed top and displays the vivid purple tones typical of amethyst. Measuring 7 × 4 × 4 cm and weighing 100 g, the specimen is a compact, hand‑sized wedge. The contrast between the drused face and the uncrushed backing gives a clear view of the crystal‑covered surface against the rough exterior. Amethyst is the purple variety of quartz (SiO2) and commonly forms drusy crystal coatings in cavity and vein settings; this background helps explain the druse texture visible on the coated face.
