The best crystal sphere for psychic readings depends on the individual's needs and preferences. Generally, clear quartz is a popular choice due to its ability to amplify energy and focus intent. Amethyst is also beneficial as it can help to open up intuition and provide clarity during readings. Rose quartz is known for its calming properties, which can be helpful in creating a peaceful atmosphere for readings. Lastly, smoky quartz has grounding qualities that are useful when connecting with spiritual energies or exploring deeper realms of consciousness. Ultimately, the right crystal sphere will depend on what resonates most with each person’s unique situation and goals.
