The mark in the first image looks a bit like Mtarfa, but not in the second.

I'm afraid I cannot make out the pattern on the stems from your photo, the background colours get in the way and they are a bit out of focus, so I cannot tell if it is a Mtarfa design - it could be. But I cannot find any Mtarfa candlesticks to see if this shape was one they made.
A sheet of white paper, or some white cloth - pillowcase, tablecloth, sheet, can be easily incorporated as a background.
And to bring up a signature or mark for photography, rub a little talcum powder or cinnamon over it with your thumb. It all helps us to help you.
I wouldn't rule Mtarfa out just yet. I think these might be consistent with their output.
