Each order comes with a free gift 🎁 Sardonyx is a chalcedony that it coloured black, red, brown and white. This cryptocrystalline quartz can be coloured with iron and carbon inclusions giving it the brown and black colouring. It is formed hydrothermally in hollows or vugs in rocks. Sardonyx is created in layers of the brown or red sard stone and the black, white or green onyx stone. This gives it a beautiful banded appearance. The word Sardonyx is derived from the Greek, sard meaning “reddish brown,” and onyx meaning “veined gem.” The best stones are found in India. They are also found in Germany, Czechoslovakia, Brazil, and Uruguay. In the United States, sardonyx can be found in the Lake Superior region and in Oregon (Healingwithcrystals.net.au)
