Shielded Wold Sapphire

Old English scild, shield — past-participle of shield, sharing root with German Schild. As a color modifier, shielded implies a saturated-and-protected-and-defensive quality, the deep-rich color of medieval-knight armorial-shield-and-coat-of-arms heraldic display. Sits at the bold-and-fortified end of the grid, parallel to armored and bastioned.

Old English wald, forested upland. As a color modifier, wold implies a chalk-upland-and-grass quality, the visual register of Lincolnshire-and-Yorkshire-Wolds chalk-and-limestone open-upland sheep-pasture-and-arable rolling surfaces under big-sky Lincolnshire-Wolds open-country light. Sits at the modifier-and-place end of the grid, parallel to moor and heath in usage.

An iron-and-titanium-bearing corundum — the same mineral as ruby, hardness 9 on the Mohs scale, mined for two millennia from Sri Lanka, Burma, Madagascar, and the Cashmere mines of British India. The color refers to a fine Kashmir-cut sapphire: a saturated, slightly violet-shifted deep blue with the gem's signature internal velvet — a quality of light scattering in the stone that faceted glass cannot replicate. Cooler than cobalt, deeper than azure.
