I use mine every so often! I have different pendulums but none really from a special or interesting gem stone! I have had really amazing readings for myself in the past which were more accurate on issues or a situation than cards but also it has got it completely wrong! so I find I cannot rely on it like divining with cards.
I read on a complex situation in my life with multiple possible outcomes, the pendulum got the outcomes spot on! better than tarot and an oracle. However I then decided that Winter to do it every day if there would be snow that day. It got that outcome wrong each time My outcomes go from amazing to just disappointing, I think you have to practice and use them a lot as part of the ritual of their use.
They are great with tarot or oracles readings though or for choosing the best deck for a reading
I had never thought to use it with choosing between decks, that is a really fab idea. I like to use the cards and pendulum in unison because I feel the pendulum often gives the definitive answer and the cards give the clarity to those answers. Maybe it was snowing, somewhere, far, far away?! ;-) We have not had much snow at all this winter in Scotland but hey, I am happy for these beautiful spring days now.
