I love realmarble floors but the engineered is certainly easier to care for so I guess I was not much help.

What are the pros and cons of engineered vs natural marble? Is it true that engineered marble doesn't become yellowish over the time?

Engineered marble is made from recycled natural stone which was crushed then mixed with resin, then heated and pressed. Natural marble is porous and requires sealing and maintenance especially if used on the floor and engineered marble is less previous to moisture and is stain and scratch resistant and it can be used on the floor. I have used it in the past for a counter in a restaurant, one job we used it on the wall in a high traffic area as wainscoting,etc

I hope it helps

Good luck

So you mean to say I can opt for engineered marble safely.

They are both safe. Engineered marble has plastic resin content. It can become yellow over time just like any other man made material.
