Bohemian/Czech mauve & purple marbled cased glass candlestick with enamel details

Here is a really cool find I made today at a flea market for just $5! It reminds me of the good old days, when bargains were easy to score...
This is an unusual tall candlestick, made from two layers of cased glass, clear over a mauve & purple marbled decor. There is orange enamel trim to the top rim & base (half worn off on that). It measures 21.4 cm tall, 7 cm across the top rim, & 9 cm across the base. No pontil mark in evidence.
I feel that this is probably a fairly rare colour, & I haven't seen anything quite like it. Have had a couple of pink marbled/streaky decor items in the past, but definitely no mauve/purple. The orange enamel details make the mauve stand out even more...it's a bold choice!
In real life the colour is much more intense, it was hard to photograph. Funnily enough I've encountered that same problem before with another mauve vase...
I think most likely Bohemian/Czech origin, early 1900s - 1920s era.
