Opals should be protected from acids, heat and dehydration, as well as cosmetics. Opals care depends on a stone with which we are dealing. Doublets and triplets consist of two (doublets) or three (triplets) layers, which are glued together. Extended exposure to water can result in stratification and destruction of the stone. They are best cleaned dry with a soft bristle brush. Glued opals should not be cleaned in an ultrasonic cleaner because they are subjected to vibrations which may also lead to the stratification. Opals should be kept in a bag from a soft material, ensuring the protection and ventilation.

Solid opals on the contrary, they like moisture, so they are held under running water and then wrapped in a damp cloth.

Solid opals can be placed in a plastic bag with a few drops of water and then wrapped in a soft cloth. This will ensure the humidity of the air. Solid opals if dried not only may lose their luster, but may even break.

These stones are best wiped with a cloth moistened with soapy water. You can not use alcohol. Dry and polish them with a soft cloth.

Jewelry with turquoise and coral can also be washed in warm water with a little baking soda. Corals can be wiped after the bath with a cloth soaked in olive oil and polish.
