Cool question Pat. I think the stuff we get in this life is already the stuff we are supoposed to get, ie., the piece of jewelry etc that you mentioned you will get if it is due to you. When I say due to you I mean your karma accounts are in balance and you are supposed to receive that particular item to learn some continuing lesson.
Since karma and reincarnation operates at below current consciousness levels for most
it may play out like you see a piece of jewelry that you feel must be yours, deja vu stuff, and then you buy it, find it, or it is gifted to you, this happens because it was meant to be yours.
I do not think we can spiritually fed ex our stuff into the next life per say, but if you love something and have earned good karma there is no reason why it should not come back to you in a next life.
