I'm considering making a set of prayer beads, and writing prayers for them, for part of the 30 Days of Deity Devotion project. I have a few ideas kicking around, but it's a bit difficult because Hestia doesn't have very many traditional associations or symbols to work from. Some deities have metals, gems, woods, numbers, and more associated with them, but Hestia has none of those. I'll have to go almost entirely from my own gut on this.
I've been running through a few options for the beads, but I keep coming back to peach moonstone. To be honest, I don't always consider the spiritual properties of stones when making prayer beads or jewelry, it's really more about color, pattern, texture, shape, overall feel, but I thought I'd dig around a bit and see what lore I could find out there on the internet specifically about peach moonstone. There wasn't a lot, and much of it seems to have been copied and pasted from the same source.
Still, what I did find seemed to always come back to the same few things; peace, soothing anxiety or worries, removing fear or anger, gentle love, and divine love, or being aware of the divine all around you. This all seems quite appropriate to Hestia, so I'm pretty sure that's the main material I'll be working with.
The rest is really still up in the air, though, I'll have to spend some more time considering the options.
