Stone
Stone means you are grounded. You prefer those that keep you feet on the ground and working with what is tangible. When working magic, you are good with your hands, creating powders, movements, and items. Keep building, crushing, and collecting. These are power strengths of yours.
In divination, Runes are a wonderful go-to for you. But you might also try divination through salt (alomancy), geomancy, cleromancy, and crystallomancy. Love the stones and gems in your life, as they will be a way for you to connect magically to the world around you and to get power to do your work.
I recommend that you start learning about gems as much as possible and surround yourself with them.
