GNEISS is a metamorphic rock marked by striking gray and red striations that ripple through its surface like the layered pages of time. These alternating bands, rich with feldspar and quartz, give it a bold, ribboned texture that tells a story of intense pressure and transformation beneath the Earth’s crust. The red tones often come from iron-bearing minerals like garnet or biotite, which contrast vividly against the cooler grays, creating a natural tapestry forged by geological forces over millions of years.This stunning tricoloré, consisting of two different shades of warm gray and a pale clay, feel striated by the earth, but softened for the fiber arts.2-ply hand-made dupioni is 1.5x the weight and twice the thickness of our standard dupioni! That means it's not only eye-popping, it's extra-strong and durable as well!
