This unique charm features a pyrite star, moss agate and a quartz crystal point. The star on the collar charm is made of pyrite, known as one of the luckiest gemstones, and it has been worn for centuries as a protection amulet by animals, and humans alike. Moss agate is an excellent source of Earth’s grounding energy during times of stress. Clear quartz is the ultimate healing crystal, and one of the most versatile and useful. It amplifies any other crystals it’s used with, and is known to raise vitality, strengthen the immune system, alleviate pain and inflammation, cleanse and purify blood, and speed up the healing of injuries. I can customize this charm (and all of my other charms) to fit your individual pet, by using smaller lobster claws and tiny crystals.
