Cleansing crystals, including vivianite, is important to clear their energy and refresh their properties. There are several methods you can use to cleanse vivianite:
Water Cleansing
Use lukewarm water and a mild soap to wash the crystal gently. Rinse it thoroughly and then pat it dry with a soft cloth. 
Sunlight Cleansing
Place your vivianite in direct sunlight for a brief period, ideally no more than 30 minutes to an hour. Sunlight can help rejuvenate the crystal's energy. Be mindful not to leave it in direct sunlight for extended periods, as this may cause fading or discolouration.
Moonlight Cleansing
Moonlight is a gentle and effective way to cleanse vivianite. Leave your crystal outdoors under the light of a full moon overnight. This method is considered safe and can be repeated as needed.
Selenite Cleansing
Selenite is a self-cleansing crystal and can cleanse other crystals. You can place your vivianite on a selenite charging plate or near selenite to help it clear any unwanted energies.
Sound Cleansing
You can use sound vibrations from singing bowls, bells, or tuning forks to cleanse vivianite. Simply ring the sound tool near the crystal. The vibrations will help clear its energy.
Visualisation
Hold the vivianite in your hand and visualise a bright, white light surrounding it, purifying and cleansing the crystal's energy.
Always trust your intuition when choosing a cleansing method for your Vivianite, and be gentle when handling it, as it is a delicate crystal. Additionally, to maintain its optimal energetic properties, consider cleansing your Vivianite regularly, especially if you use it frequently for healing or energy work.
Vivianite can be sensitive to water and significantly extended exposure to moisture. It is essential to exercise caution when considering water-related activities with Vivianite. 
Vivianite should not be soaked in water or submerged for extended periods. Prolonged contact with water can cause vivianite to degrade, soften, or lose its lustre over time.
Vivianite is not typically associated with a specific zodiac sign. However, you use Vivianite based on its properties or energies rather than its zodiac sign.
Vivianite is not one of the traditional birthstones associated with specific months. However, if you have a personal connection to Vivianite or find its energy resonates with you, you are certainly welcome to consider it your unique birthstone or a meaningful crystal for your birth month. The choice of a birthstone can be a personal and symbolic one, and there are no strict rules governing which crystals or gemstones you can choose to represent your birth month.
