MINERAL & GEOLOGICAL DETAILS – AMETHYST (QUARTZ VARIETY)Amethyst is a purple variety of Quartz, composed of silicon dioxide (SiO₂). It crystallises in the trigonal crystal system and commonly forms six-sided prismatic crystals terminating in pyramidal points in its natural state. The purple colour is caused by trace amounts of iron within the crystal lattice, combined with natural irradiation during geological formation.Amethyst forms primarily in igneous rock environments, particularly within cavities of basalt and other volcanic rocks. Over millions of years, silica-rich fluids deposit layers of quartz crystals inside these voids, often creating geodes lined with well-formed crystals. It can also occur in hydrothermal veins and pegmatitic formations.Colour variation ranges from delicate pale lilac to deep violet and rich royal purple. Some specimens may show subtle colour zoning, where tones shift within the stone. Amethyst is typically transparent to translucent with a vitreous (glass-like) lustre. Natural inclusions, internal fractures or faint veils may be visible and are part of the crystal’s geological history.Hardness: 7 on the Mohs scaleCrystal System: TrigonalLustre: VitreousTransparency: Transparent to translucent JEWELLERY DESIGN – CLASSIC 18 INCH NECKLACEThe 18-inch length is one of the most popular necklace sizes, offering a balanced and elegant drape suitable for both everyday wear and formal occasions.
