Amethyst is purple, pink, violet or a mauve variety of crystalline Quartz and has been associated with royalty throughout history. Amethyst is the most highly valued stone in the quartz group. The name is from the Greek amethysts, meaning sober. The hardness of amethyst is 7 and its commonly used in jewellery due to its beauty. Amethyst can be found as record-breaking crystal in geodes so large you could stand inside them. These huge pockets from as gas bubble from cooling lava flows get frozenness. Later silica-rich solutions fill voids and deposit crystals. Quartz is one of the most common minerals on Earth. Other varieties of Quartz include Ametrine and Citrine. Amethyst comes in a variety of colors, from pale violet to deep purple with red flashes. The colour is due to trace amounts of iron impurities added to the basic silicon dioxide formula.
