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. 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.
