Chestnut leaf earrings with Amethyst (brass hand made)

▲▲▲ Amethyst Geological Properties Amethyst is a naturally-occurring macrocrystalline (meaning large crystal formations) variety of quartz that usually grows on the inside of agate geodes. Geodes containing amethyst crystals are formed when clay, silt, sand or gravel are deposited and compacted by running water. While the crystals themselves may grow to be several inches, the geodes containing the amethyst crystals often reach several feet in height. Some of the largest amethyst geodes have been found in Brazil. This majestic gemstone gets its color from the presence of manganese and/or iron. Amethyst can also appear reddish-purple or yellow-purple depending on the combination of minerals present in the clear quartz. Were amethyst less abundant, it would be even more highly-prized--and expensive!
