Imperial Virgo Ruby

From the Latin imperialis, of the empire — applied to color since the medieval period for the hues reserved for sovereigns and empires: imperial purple of Tyrian dye, imperial yellow of Ming-dynasty porcelain. As a modifier, imperial implies saturation combined with the institutional weight of a color owned by a court. Sits in the bold-and-deep corner, alongside royal.

Latin virgo, virgin-or-maiden-of-the-zodiac. As a color modifier, virgo implies a maiden-and-earth-sign-and-Mercury-ruled-mutable-earth quality, the visual register of Hellenic-Virgo-and-Astraea-maiden hand-maiden-and-earth-sign-and-Mercury-ruled-mutable-earth Hellenic-Virgo-and-Astraea-maiden-and-Spica-grain virgo-and-maiden-and-earth-sign surfaces under Hellenic-Virgo-and-Astraea-maiden-and-Spica-grain late-summer-and-August-and-September mutable-earth-sign-light. Sits at the modifier-and-zodiac end of the grid, parallel to leo and libra 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.
