Sumptuous Blink Sapphire

Latin sūmptuōsus, expensive — derived from sūmptus (expense). As a color modifier, sumptuous implies a saturated-and-rich-and-luxurious quality, the deep-rich color of Burgundy-and-Champagne-Court late-medieval silk-and-velvet livery in the Très-Riches-Heures manuscript tradition. Sits at the bold-and-saturated end of the grid, parallel to opulent and lavish.

Middle Dutch blinken, to-shine-or-twinkle. As a color modifier, blink implies a quick-and-twinkling-and-on-off quality, the visual register of lighthouse-beam-and-firefly-blink hand-quick-and-twinkling-and-on-off lighthouse-beam-and-firefly-and-Morse-lamp blinked-and-quick-and-twinkling surfaces under lighthouse-beam-and-firefly-and-Morse-lamp coastal-headland-and-summer-meadow rotating-and-pulsed-light. Sits at the modifier-and-mood end of the grid, parallel to wink and glint 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.
