Crystal Type – Genuine Amethyst (Quartz Variety)

Amethyst is a macrocrystalline variety of quartz recognised for its striking violet-to-deep-purple colouring. Its colour arises from trace amounts of iron subjected to natural irradiation over millions of years, creating the signature hues associated with this gemstone. As an A-grade polished specimen, this pebble highlights the crystal’s natural translucency and rich saturation.

Key gemstone characteristics:

• Mineral Species: Quartz (Amethyst variety)
• Group: Silicates
• Chemical Composition: SiO₂ (silicon dioxide) with Fe³⁺ inclusions
• Crystal Habit: Typically prismatic hexagonal crystals; in this case, polished from naturally massive quartz
• Hardness: 7 on the Mohs scale
• Lustre: Vitreous before polishing; high-gloss finish after hand shaping
• Colour Range: Lavender, plum, to deep violet banding

This pebble has been polished to a smooth, tactile finish, making it ideal for holding, displaying, or use as a comforting palmstone.

Geological Background – Formation & Origin

Amethyst forms within volcanic and hydrothermal environments, where silica-rich fluids cool and crystallise inside geodes, cavities, or fractures in igneous rock. The deep purples are influenced by natural iron impurities and geological radiation over long periods of time. This slow crystallisation process produces the layered colour zones and internal clarity variations commonly seen in high-quality Amethyst.

Formation Environment:

• Typically forms in basaltic lava flows containing hollow cavities
• Silica-rich solutions enter these cavities and crystallise into quartz
• Iron impurities undergo irradiation, producing Amethyst’s purple coloration

Colour and Pattern Development:

• Light lavender zones come from lower concentrations of iron
• Deeper violet bands indicate higher iron density
• Natural inclusions such as wispy veils or tiny fractures add individuality

Each Amethyst specimen carries its own geological story shaped by millions of years of mineral formation.
