Patagonian Rosewood flooring, originating in the forests of Paraguay, is also known as Curupau. Solid Patagonian Rosewood hardwood has pale pink and yellow tones. You'll also notice dark brown shades and occasional black streaking to go along with the hardwood's crossed grain, thus creating a beautiful combination of rich browns and yellows. Patagonian Rosewood hardwood flooring is very durable. The wood's Janka hardness rating of 3,840 makes it stand up against daily wear and tear.
