Lukewarm soapy water is the best for cleaning this stone, but it doesn’t tolerate long periods in bright sunlight, the colour can fade. Place on ground from time to time. Household chemicals and perfumes are not a friend of any crystal. Fragrance-free oil is good sometimes.
If you wear it as jewellery, it is enough to discharge it under flowing water 1–2 times a month and let it recover shortly in the sunshine or longer in the moonlight. Admire your crystal and program above candle light or with insence.
