To make your moldavite active, focus on purging it. Moldavite, a natural glass formed from a meteorite impact, can be cleansed by exposing the gem to moonlight or sunlight, burning sage, or clearing it with selenite or clear quartz. After cleaning it up, charge your moldavite by burying it for a night to absorb energy from the earth and moon. Another method that works well is putting it over a bed of natural materials like soil or sand. One can also meditate with his/her moldavite while focusing on the intention of infusing their energy into them. Consistently repeating these steps will maintain its strength and potency. Additionally, it's essential to learn how to spot fake moldavite to ensure you are using genuine moldavite for these practices.
