Tapered cut-glass pendant with multi-facetted cutting, in the shape of an icicle.

Named after the Prince Regent, later George IV, circa 1810 to 1830, the term is also used more widely to describe the prevailing English neo-classical style between the 1790s and 1840. In lighting, they used multiple cut-glass prisms to achieve as many reflections as possible such as 'double-stars' and 'icicles'. Two chandelier designs typical of this period are the colza oil dish light and the balloon-shaped chandelier with graduated chains of prisms.

The literal meaning in French is 'chandelier', or 'shine'; in English, 'radiance' or 'reflected light'. This word is also used for a cut-glass candlestick, usually with a fringe of cut glass prisms.
