Clear Quartz, also known as a master crystal and master healer crystal, is the most versatile crystal you can have in your collection as it can be programmed for any purpose from prosperity to protection. You can also use it to amplify other crystals and any ritual work or healing.
The flame is such a powerful and beautiful symbol, especially in Carnelian. It can be used in many ways, but I love to hold against my Sacral Chakra and see the energy flowing out from the flame surrounding you in a flame of energy with your intent. This energy can be sent around just yourself or your entire home, check out my You Tube video where I talk about flames in more detail.
