When heavy items like furniture or appliances are dragged or rolled across true geological marble, deep white lines in the stone form. These marks are referred to as stunned crystals. They cannot be removed.
Frequently these marks are caused by moving large pianos. The marks pictured were made by the largest pianio I have ever seen.
We advise customers to have enough lifters on hand to manhandle these items as rollers are not designed to be used on stone floors.
