A general rule of thumb is that if it ends in ite', it's safe to say it cannot be immersed in water for long periods. There are other crystals that don't end in ite' too that shouldn't be immersed in water for too long so do your research, or drop me a message and i'll check for you there are certain crystals that have the ability to cleanse other crystals, such as selenite, or carnelian, if you place your crystal alongside these then it will keep them at optimal energy frequencies for you.
Once you have cleansed your crystal, you can programme' it by meditating and manifesting your intentions and desires into the stone. Just repeatedly tell your crystal what you are manifesting and be as specific as you can. They are perfectly imperfect as nature made them so also, please don't leave your crystals in direct sunlight for prolonged periods over time.
Their bright and beautiful colours may fade over time as they are formed in darkness. All packaging used is fully recyclable. This item is made of larimar.
