Radiant Shine Peridot

From the Latin radiare, to emit rays — used as a color word since the seventeenth century for hues that read as luminous and emitting. Radiant gold, radiant pink: the implication is high luminance combined with the optical impression of an outward light. Sits in the bright-bucket center alongside glowing.

Old English scīnan, to-shine. As a color modifier, shine implies a polished-and-reflective-light quality, the visual register of polished-silver-and-bronze-shine hand-polished-and-buffed silver-and-bronze-and-brass-and-tin polished-and-reflective-shine surfaces under polished-silver-and-bronze-shine workshop-light. Sits at the modifier-and-texture end of the grid, parallel to gloss and sleek in usage.

The transparent green variety of olivine — the gem mined from Egyptian Zabargad Island since pharaonic times and now from arid mountain ranges in Pakistan, Arizona, and Vietnam. The color refers to a faceted peridot: a clean, slightly yellow-shifted green with the gem's signature internal warmth. Lighter than emerald, brighter than olivine in its rough state, with the unusual gem-trade quality of being one of the few minerals that occurs in only one color.
