Chicken crystal: topaz green ghost hair crystal Dongling jade amethyst
If you want to help peace, you can choose jadeite garnet, black spar and white crystal.
To sum up, topaz is a good choice for you. This is the only one based on constellations and animal signs.
Besides, I don't know what you want the crystal for, so it's hard to say. If you don't understand, continue Baidu!
Although many people say that crystal has no effect, I still believe it. There are many at home, and I like them very much. Just like it!
