BECAUSE IT REFLACTE LIGHT IN BRIGHT AREA

shannonsshizzle2017: Light striking the diamond at an angle gets refracted, or bent, as it enters the stone. ... Parts of the visual cortex respond strongly to high intensity contrast edges, and so the close proximity between brightly lit and very dark facets enhances the perceived brilliance of a diamond

The diamond glows due to TIR. When the room is lit it recieves light and goes through with the total internal reflection and shines bright.

But in case of a dark room, the diamond recieves no light and therefore no TIR and thus it does not shine in dark
