Mod off-center circle candle holder, retro smoke grey glass, vintage Viking

We've been told that this vintage smoke grey glass candle holder is Viking?, though we don't know the name of this mod asymetrical pattern? The candle would stand off-center on this glass candleholder, with plate 9 1/2" in diameter.

This is in perfect condition without damage. We love the grey-green smoke color, very retro!
