The Cast Naturals Collection highlights our skills at taking an innovative material and making it feel as if it sprang from nature. The Square Root Medium Silver Wall Art is made of composite that has been molded to look like a piece of harvested wood it took nature ions to create, then finished in silver leaf. The advantage of having a decorative accessory made from this durable material is that it will long outlast its natural counterparts pulled from the forest floor. This piece of wall art is the perfect representation of the Phillips Collection ethos: modern organic. We have Square Root products in a number of configurations and finishes.
