REFULGENCY — [Noun] The quality or state of shining brightly; a sustained, intrinsic, and splendidly radiant brilliance. From Latin refulgentia, from refulgēre ("to shine brightly"), from re- (intensive) + fulgēre ("to shine, glitter"). Unlike effulgence, which implies an outward, overwhelming burst, or luster, which suggests a softer, reflected sheen, refulgency describes an intrinsic and steadfast radiance. It is the liquid gold of late afternoon sun pooled on marble, the steady, cold gleam of a planet seen through a telescope, or the perfect, contained fire of a flawless diamond—a quiet conflagration, a splendor perfected within its form and held intact against the gathering dusk.
