@lioness I ordered for my husband off Amazon beautiful Santorini stone. Small pieces different shapes, I bought a package of three. White and has a slight sparkle ( reminds me of an opal) . Great background color. Paint/pen colors really “pop” ( my husband’s new word, learned it from watching all the remodeling shows on tv🤣🤣) check it out. Tell your friend. It’s a different surface. These are very compatible/like to regular unpolished rock. Your polished stone will be more of a challenge but very doable if you want to try it. Have a good one
