Black agates with white bands are distinct from Onyx in that they have curved or non-parallel stripes - Onyx only has parallel bands. Onyx is sometimes considered a precious gem, and it is especially prized by gem carving artists in the creation of cameos. Most Onyx on the market today has been treated or dyed to enhance the black color and make the color uniform throughout the stone. Onyx is found all over the world including the USA, India, Brazil, Germany and China.All photos have been taken indoors with daylight, but as always, computer and mobile screens display colors differently.
