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. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
