A cross-section of brown agate reveals concentric bands of warm tan, cream, and charcoal that radiate outward from a sparkling crystal-lined center cavity against a dark ground. Gold foil accents trace the geometric layers, creating luminous linear patterns that emphasize the stone's natural formations and mineral deposits. Constructed from woven polyester with a soft microfiber lining and a sturdy zipper, made to order for 13 and 15 inch laptops. Everyday protection carrying an independent artist's work, not another plain black sleeve.
