Opal Maintenance Method

1. Although the main component of Opal is also SiO2, it contains H2O and is amorphous. Its hardness is much lower than that of crystalline crystal. It is easy to be abraded and loses its surface gloss. Therefore, it should avoid rubbing with other hard things. Do not mix with other jewelry when saving.

2. Since the water in the opal belongs to the adsorbed water, its escape temperature is only 100 ° C - 110 ° C. Although the water in the opal does not escape during the daily wearing process, the water in the long-term high temperature or low humidity environment is easily lost, resulting in loss of color, dullness and even bursting. Therefore, it is not suitable to be exposed to fire or high temperature during processing or wearing. It should not be exposed to sunlight. Try to wear as little as possible in areas that are too dry. For the original stone, it should be stored in water. If the jewellery counter is equipped with light sources such as spotlights, water cup should be placed to keep the humidity.
