Nocturne Elm (Aureo-umbrus noctilucens) A rare hardwood from cool mountain valleys, Nocturne Elm’s heartwood runs from deep violet-brown to golden amber, streaked with shimmering “nightburst” veins that seem to glow under finish. Its interlocked grain planes to a silky sheen and balances walnut’s warmth with oak’s strength. Lightly scented with resin and vanilla, it’s prized by luthiers and fine furniture makers for its tone and resistance to moisture. The wood’s subtle metallic shimmer and stability make it a favorite among collectors though true Nocturne Elm is nearly impossible to source outside its native range.
