Etch marks are very common on marble or stone surfaces, especially after acid etch marking is done by amateurs without proper experience. Each marking is a process in which acid etchant (muriatic Acid HCl) dissolves etched surfaces and creates microscopic grooves.
Etch marks, however, are not watermarks, but the two can be confused easily because they both create similar patterns on stone, marble or other surfaces. Water marks are caused by a sudden change in humidity or temperature, most commonly a very low humidity situation. After a long period of time under low humidity, water marks can appear identical to etch marks.
