#amethyst

• Amethyst — A violet, purple, or lilac semi-precious macrocrystalline variety of quartz, whose coloration is due to iron and titanium impurities combined with natural irradiation within its trigonal crystalline structure. This structural mineral is widely utilized in jewelry, high-end decorative crafts, and is valued in crystal healing for its symbolic calming properties.
• Amethystine — The feminine singular form or a rarely used adjectival variant to qualify an entity, shade, or decoration presenting the purple-violet color characteristic of amethyst; also, in older poetic or niche nomenclature, it describes a fine textile or mineral chromatic variety borrowing the shine of this quartz.
