It is recommended to remove your emerald jewellery before household cleaning since this gem is sensitive to chemicals such as ammonia, alcohol, bleach and other acids. Also, it is better to remove your emerald jewellery before exercising and other physical activity, as it can be scratched by other harder materials.
As a general rule, you should put your emerald jewellery on last when dressing. Chemicals from makeup, hairspray, perfume and body creams can change the gem’s colour or make it look hazy. Putting your jewellery on should always be the last step.
