Hi Sandee,
I think you are looking for some very specific advice here. Usually I would never just suggest one stone based on the astrology of a person. I take the whole person and situation into consideration, I use crystals holistically. But your sign would do very well with moonstone and also ruby. Red coral is very temperamental, being organic it can vary greatly but it is very useful for women especially anything linked to pregnancy and getting pregnant, it is fire and hot and so almost the opposite to the watery, insecure, home loving crab sign. Perhaps this is why it was chosen or perhaps it fills a gap that you need.
My advice would be to listen to yourself and make your decision, I am sure that you know the right stones for you.
