Decisive Sagittarius Ruby

From the Latin decidere, to cut off — used as a modifier for colors that read as firm and final. Decisive black, decisive red: the implication is that the color has settled on its position and won't drift. Sits in the bold-bucket corner alongside resolute, with a slightly sharper edge.

Latin sagittarius, archer-of-the-zodiac. As a color modifier, sagittarius implies a centaur-archer-and-fire-sign-and-Jupiter-ruled-mutable-fire quality, the visual register of Hellenic-Sagittarius-and-Chiron-centaur-archer hand-centaur-archer-and-fire-sign-and-Jupiter-ruled-mutable-fire Hellenic-Sagittarius-and-Chiron-centaur-archer-and-galactic-center sagittarius-and-centaur-archer-and-fire-sign surfaces under Hellenic-Sagittarius-and-Chiron-centaur-archer-and-galactic-center late-autumn-and-November-and-December mutable-fire-sign-light. Sits at the modifier-and-zodiac end of the grid, parallel to scorpio and capricorn 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.
