Many small diamond facets, which again make a large diamond. In addition, the purple-colored seindenmatt iridescent coated colored glass - if that is not royal, what is? ..... Likewise, I can imagine this candlestick well in royal blue, although I would probably again opt for the purple red.
Of course, you can apply the design to any other color.But I recommend a glass as contrasting as possible to the clear glass facets.
