Amethyst druzy heart carvings

This listing features carved amethyst druzy specimens shaped into hearts, showcasing a range of natural colour variations from deep charcoal and smoky tones to soft lilac and pale lavender hues. Each piece displays a sparkling druzy surface formed by tightly packed crystal points, set on a visible quartz matrix base.

Geological & Scientific Notes

Amethyst is a quartz variety formed from silica-rich fluids within cavities of volcanic rock. The variation in colour seen across these pieces is due to differences in iron content and natural radiation exposure during formation, resulting in tones that range from very pale to deep, almost black hues.

The druzy surfaces consist of numerous small, naturally formed crystal points (euhedral terminations) that grew inward from the cavity walls. This micro-crystalline structure creates a textured, light-reflective surface that gives each piece its characteristic sparkle.

Visible matrix material and occasional mineral inclusions or staining (such as iron oxides) may be present, reflecting the natural geological environment in which the crystals formed.
