A comprehensive grid of mineral specimens and gemstones rendered in soft watercolor and fine line work fills this vintage scientific illustration, each specimen labeled and arranged in neat rows against a cream background. The palette of ochres, purples, teals, and blacks captures the natural variety of crystalline forms, from translucent gemstones to rough ore deposits, creating a scholarly cabinet of curiosities frozen in time. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
