It is better not to recommend this. Selenite is a form of gypsum, which is slightly soluble in water, so prolonged contact with moisture can gradually damage or dull the surface.

Use a soft, dry cloth or brush for routine dusting. Avoid soaking, rinsing under running water or using wet cleaning methods unnecessarily; if a mark needs attention, use as little moisture as possible and dry the bowl immediately.

Yes. Gypsum is only around 2 on the Mohs hardness scale, meaning selenite is considerably softer than many common minerals and household materials. Handle display stock carefully and avoid stacking bowls directly against one another, as rubbing can mark polished surfaces.

Yes. Selenite has pronounced cleavage and is relatively brittle, so impacts can cause chips, cracks or pieces to split along natural planes. Larger bowls should therefore be displayed on stable shelving away from edges and busy walkways.

These bowls are not specified as candle holders, incense burners or heat-resistant vessels. Retailers should therefore not recommend placing flames, charcoal, hot wax or burning incense directly inside them; purpose-made heat-resistant holders are the appropriate choice.

No, they are better treated as decorative bowls rather than serving ware. This is particularly worth explaining where the round and heart-shaped designs might otherwise be mistaken for conventional tableware.

Selenite has many associations within crystal and spiritual practices, including ideas around cleansing, clarity and calm. These should be presented as traditional or spiritual beliefs rather than scientifically established health benefits, and retailers should avoid making medical or therapeutic claims.
