Opal jewellery requires no greater care than other jewellery mounted with stones such as Diamond, Ruby, Emerald, Tanzanite or Turquoise.
You should never wear any jewellery in rough conditions such as to the beach or during activities where it may get knocked by metal or hard objects (e.g. washing up).
In these conditions, stones get dislodged from their settings, gold gets scratched and stones get chipped (even diamonds) and Opal should be treated the same as all other stones – with respect.
Opal requires no special treatment or care. As with other stones, grime from wear can be wiped off with a damp tissue or cloth.
