Amethyst cluster small

This natural amethyst cluster features a soft blend of pale lavender and near-clear quartz crystals, forming a compact and sparkling display piece. The crystal points are slightly larger and more defined than fine druzy, creating a textured surface that catches the light beautifully. Set on a natural quartz matrix, the piece retains its raw, organic shape with earthy tones along the outer edge.

Geological & Scientific Notes
Amethyst is a variety of quartz that forms in cavities within volcanic rock, where silica-rich fluids slowly crystallise over time. The lighter purple tones seen in this piece suggest lower iron content and more subtle natural irradiation during formation.

This cluster displays well-formed crystal points that grew inward from the cavity walls, resulting in a layered, dimensional structure. Compared to finer druzy, these larger points create a more defined, geometric appearance while still maintaining a gentle sparkle.

The surrounding white to translucent quartz matrix and earthy outer layer reflect the host rock in which the amethyst formed. These natural inclusions and colour variations provide insight into the geological environment and mineral deposition process.
