Heavy Dill Tanzanite

Old English hefig, weighty — cognate with heave. Used as a color modifier since at least the seventeenth century to indicate weight in saturation as much as value: heavy with pigment, heavy-bodied. In the engine's adjective grid, heavy sits alongside deep and plush in the dark-and-saturated quadrant. Closer to a fabric description than a pure value word.

Old English dile, aromatic-fern-leaf-herb. As a color modifier, dill implies a feathery-and-fresh-and-pickling quality, the visual register of Scandinavian-and-pickling-dill hand-feathery-and-fresh-and-pickling Scandinavian-and-pickling-dill-and-Polish-Eastern-European dill-and-feathery-and-fresh-and-pickling surfaces under Scandinavian-and-pickling-dill-and-Polish-Eastern-European Stockholm-and-Gdansk-and-Riga-pickling-jar Baltic-pickling-light. Sits at the modifier-and-flavor end of the grid, parallel to chive and anise in usage.

A blue-violet variety of zoisite — discovered in 1967 in a single small area of northern Tanzania near Mount Kilimanjaro and marketed by Tiffany & Co. shortly after. The color refers to a faceted tanzanite cut to maximize its strong pleochroism: a saturated, slightly violet-shifted deep blue-purple with the gem's signature internal life. Cooler than amethyst, warmer than iolite, with the gem-trade specificity of a stone that occurs in exactly one place on Earth.
