The Abrielle Serving Board w/Knife by Bloomingville is made of white marble and comes with a small butter knife. Use it as a serving tray or as the perfect gift idea. The beauty of a natural stone is that no two pieces are exactly alike. Each one is a unique work of art forged by Mother Nature over millennia using heat, pressure and lots of different minerals and organic materials. The way these minerals settle into the stone is what causes the huge variety of colors, patterns, textures and veins in each slab.
