I am not a numerologist so can't directly speak to your question.
I do work with crystal and stone energies also, however, and have noticed something that might be of interest to you. Various stones coordinate with certain energies of the zodiac, (example: Malachite is a Scorpio stone) and I have noticed that people are frequently drawn to stones and crystals that vibrate with an energy vibrating not with energies of their own sign, but with energies they lack from the other signs.
I have no Earth signs in my chart and find time after time after time that I am drawn toward stones I find out later are affiliated with the Earth signs, which makes sense because that is where I most lack, and their energies balance and round me out.
As I read your post, it seems that we have hit upon the same dynamic... I find that interesting.
