Agate is a variety of chalcedony (silica, SiO₂), characterised by its fine grain and vivid colour banding. These striking patterns are formed over millions of years as silica-rich solutions fill cavities within volcanic rocks. The layered deposition creates the unique concentric bands that make agate one of the most recognisable and collectible minerals in the world.
Geological Information:
- Mineral Type: Silica (Chalcedony, a cryptocrystalline quartz)
- Formation: Occurs as nodules within volcanic rocks and ancient lavas
- Hardness: 6.5–7 on the Mohs scale
- Lustre: Waxy to vitreous when polished
- Colours: Wide range – natural tones include grey, brown, black, and cream; enhanced slices may feature vibrant pink, blue, or purple hues
Dyed vs. Natural Agate:
- Dyed Agate Slices: Brightly coloured specimens (pink, blue, purple, etc.) are genuine agate that has been cut, polished, and colour-enhanced through dyeing to highlight the natural banding.
- Natural Agate Slices: More subdued in tone (brown, black, grey, or earthy colours), these pieces are completely natural with no colour enhancement.
Brazil is one of the world’s most famous sources of high-quality agate, with deposits producing specimens ideal for carving, jewellery, and decorative art. Throughout history, agate has been valued not only as an ornamental stone but also as a protective talisman. Today, it remains a favourite among collectors, jewelers, and crystal enthusiasts alike.
