The black and white stone is zebra jasper from Rajasthan (India). Zebra jasper is a type of marble. A similar looking stone can also be found in the USA but it's believed to have a slightly different chemical composition.

Many stones are given trade names to boost popularity. The problem with this from a geological perspective is that many are misleading or inaccurate.
