? about creating an energy field for charging

I've been reading The Seven Secrets of Crystal Talismans
ISBN: 978-0-7387-1144-7

In the section on the Sixth Secret, Henry Mason talks about rituals at Stonehenge at specific times of the year. I was wondering what effect might be created by using Natal Chart Jewelry (like those made by Alicia at Wandering Star) as the "ring of stones" surrounding during a charging or dedication ritual.

I really am tempted to make up the charts for the equinoxes & solstices of the year of my birth. Are there any other years or times that you think might yield interesting energies?
