Our gem wall tiles could not be more representative of the ethos that Phillips Collection personifies: modern organic. Available in a wide array of stones and configurations, not only are they powerful hung singly, they are a knock-out when used to create a mosaic gallery wall configuration. The Gem Sand Onyx Stone Wall Tile in this collection is a caramel colored hue with fluid veining along its surface. This makes each of these one-of-a-kind, which is why the decorative wall art is designated assorted. Just like a real gem, it is fastened with a brass setting.
