Gemstone points raise energy upward, from your Root to Crown Chakra. Low vibrations have a hard time maintaining in high vibration space, which is one of the goals in working with gemstones carved into points. These rough points keep the vibration high which promotes positive energy and protection.
Smoky Quartz is a protective and grounding Root Chakra stone that transmutes negative energy and purifies your aura. It’s a powerful healer that absorbs the energies the body cannot take or hold on its own. I’ve even seen it help with the side effects of different medical therapies including chemotherapy. It’s like the gem version of a best friend.
