Chivalrous Vela Ruby

Old French chevaleros, knightly — adjectival suffix -ous, derived from cheval (horse). As a color modifier, chivalrous implies a saturated-and-knightly-and-gallant quality, the deep-rich color of medieval-Romance chanson-de-geste hero-and-troubadour song tradition. Sits at the bold-and-chivalrous end of the grid, parallel to gallant and knightly.

Latin vela, sails-of-the-Argo. As a color modifier, vela implies a southern-hemisphere-and-Argo-sail-and-supernova-remnant quality, the visual register of Vela-supernova-remnant-and-Argo-sails hand-southern-hemisphere-and-Argo-sail-and-supernova-remnant Vela-supernova-remnant-and-Argo-sails-and-southern-Milky-Way vela-and-southern-hemisphere-and-Argo-sail surfaces under Vela-supernova-remnant-and-Argo-sails-and-southern-Milky-Way Southern-Cross-and-southern-zenith southern-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to cygnus and draco in usage.

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.
