Yes, amethyst is a type of mineral belonging to the quartz family. It is a variety of quartz that has a purple color due to the presence of iron impurities in its crystal structure. Amethyst is commonly found in geodes and volcanic rock formations.
Nitric acid reacts with quartz to form silicon dioxide (SiO2) and nitric oxide gas (NO).
Gems are made of a variety of minerals. Here are a few examples.Diamond: native element: carbonRuby/Sapphire: oxide: corundum (aluminum oxide, Al2O3)Emerald: Cyclosilicate: beryl (beryllium aluminum silicate, Be3Al2(SiO3)6)Amethyst: oxide/tectosilicate (quartz, SiO2)
silicates, tectosilicates and it may be considered as an oxide
Dark orange quartz is typically known as carnelian. It is a variety of chalcedony that ranges in color from pale orange to deep red-orange due to the presence of iron oxide impurities. Carnelian is believed to promote courage, vitality, and creativity.
Pure quartz is homogeneous. However, so-called quartz rocks found in nature are usually heterogeneous.
Pure quartz is a colorless mineral, and so a pure quartz sandstone will appear white due to multiple reflections and refractions between grains. However, impurities in the sandstone may give it some other color. What color it turns out as depends on the impurities. For example, iron oxide will produce a red sandstone.
Zinc carbonate or zinc oxide is coloured pink with ferric oxide to make calamine powder.
