Personally, I'd say the Ace of Pentacles showed the potential for manifestation. I'd need surrounding cards to make an actual prediction, though, because the Ace of Pents is a contradiction to me---Pentacles show me real, true, manifested things/experiences/creations, but Aces show me potential that may or may not be realized. So, I guess it means the potential is real, but whether or not it is MADE real remains to be seen.
For me, pentacles have never represented work/career/money so much as things that are tangible. They come up in those topics so often because money is a very tangible thing---it's an idea made real and represented by objects. But a ring is a real symbol of a marriage, so it's a "Pentacles"y thing as well, you know? (Granted, that's not in the Aces IMO). So, it can definitely be your answer, but it kind of answers in a non-answer sort of way. Kind of saying "There's real potential to create here, but the future is what you make of it."
