Brass is an alloy of copper Cu and zinc Zn, two elements from the periodic table. Because it contains copper, brass also has antiviral and antibacterial properties similar to copper and can conduct electricity.
Amethyst is a member of the quartz family of gemstones, which also includes citrine, agate, ametrine, chalcedony, rock crystal quartz, smoky quartz, rose quartz and various dyed quartzes. Amethyst is formed when oxygen and silicon crystallize together, along with iron particles which contribute to the purple variety of quartz. A geode has many small quartz crystals concentrated together where the crystals can clearly be seen with the eye. Druzy quartz occurs when many small quartz crystals are concentrated together but the crystals are much smaller and appear similar to a sugar crystal surface.
