A cross-section of purple agate reveals concentric bands of deep violet, lavender, and cream, layered with delicate striations and natural mineral deposits that create an almost geological map. Golden deposits accent the upper edge while the composition centers on the stone's dramatic curved patterns, captured with the precision of nature photography that celebrates the raw geometry hidden within the earth. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
