Google "Rainforest Brown" and it can come back with a confusing result... is it granite? Or is it Marble? Technically Rainforest Brown is a Serpentine. Which can be even more confusing. There is plenty of information about granite countertops and even marble countertops. Serpentine is said to be harder and more durable than marble. In fact it's recommended that it be cut with a granite blade instead of a marble blade. It will not stain or scratch as easily as marble either.
Here is a beautiful example of Rainforest Brown Kitchen Countertops.
A project we finished earlier this year and LOVED!
