Yellow Apatite brings a sunny disposition and can bring invigorating feelings and the motivation for a fresh start. Its energy is one of optimism and clarity and wonderful to use in grids or medicine bags when you need inspiration, motivation and the courage to tackle obstacles or issues that you have been pushing aside.
The small are about 3/4" and the small/medium about 3/4" to 7/8"
They have lovely Cat's Eye chatoyancy and two or three of these tumbled stones would make an excellent addition to a crystal grid or medicine bag :)
Like all my crystals these stones have been re-tuned with vibrational sound and then bathed in moonlight in one of our copper pyramids.
