Rutilated Smoky Quartz points are a good brown colour and with some clarity as two sides of them are in the process of turning into a phantom layer. These are a nice size for holding and altars.
I mainly intuit smoky quartz to ground all those lovely thoughts in an “in the mind” personality like me. I see it as rooting rather than just grounding your energy. And therefore they can relax, be more level-headed, and receive new ideas. It gently neutralises negative vibrations. It is detoxifying on all levels this then prompts elimination of the digestive system.
They have some golden rutile which can clear energy blockages of all the chakras, then energize them. It stimulates the alignment of the mind and body. The crystal helps to strengthen your willpower and motivation.
