This slice is cut from natural agate and enhanced with an aura coating that gives it a shimmering, iridescent finish. Agate is a variety of chalcedony known for its banded patterns, which form as layers of silica are deposited in cavities within volcanic rock. The added aura treatment creates a rainbow-like surface effect while preserving the natural beauty of the stone.
Details:
- Material: Agate (SiO₂) with aura coating
- Size: Approximately 5–6 inches in diameter
- Appearance: Polished slice displaying natural banding patterns with an iridescent, rainbow-like sheen
- Formation: Agate forms when silica-rich fluids deposit microcrystalline quartz in layers; the aura effect is achieved through vapor deposition of metal onto the surface
- Physical Properties: Mohs hardness 6.5–7; vitreous luster; durable and smooth surface
- Educational Value: Demonstrates both natural agate banding and modern enhancement techniques that highlight mineral surfaces with iridescence
This aura agate slice combines natural geological beauty with a striking, colorful finish, making it both decorative and educational.
