Thanks folks for your replies and suggestions

I'm not sure about Wedgwood colours, but can't find a match in shape/design for them. Ive looked at Caithness - again no match although they appear to have a colour called 'soot' which I like. I use to have a good link for King's Lynn glass but seem to have lost it unfortunately. I've had a quick search for candle holders made by German glass companies, at least the ones I have recorded in my little notebook but without success as yet, so still searching.
I'm a bit reluctant to use an actual candle as I agree it doesn't look safe. At the moment it has an LED "candle" in it, but they just don't give off the same lovely glow that wax candles do. I'll be digging out all my glass candles for Christmas, using LED alternatives. Much safer with visiting grandchildren. There's a large box of Kosta Boda snowball candleholders somewhere in the garage which will be making their yearly appearance. I think I'm well into double figures with those. They don't look too bad with LEDs.
Thanks once more
