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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe druzy surfaces consist of numerous small, naturally formed crystal points (euhedral terminations) that grew inward from the cavity walls.
