Your help needed to identify candlesticks

Hi there. I have owned this pair of candlesticks for a while now and I have always wondered if they are Machine age candlesticks? They are made of brass and each candlestick has 9 coloured (glass?) beads? on them. Are they perhaps alter candles?
They look to have age to them.
I am just wondering if anyone else has seen or knows anything about these type of candlesticks? or has any information on candlesticks like these?
thank you
