To preserve your jewellery, take it off before strenuous activities like gym, washing hands or using chemicals.
Avoid lotion, perfume, hair spray or other cosmetics from coming in contact with the jewellery.
Be sure to take off your jewellery before sleeping, showering, swimming, participating in sports activities, or any activity that requires contact with water or moisture.
When not worn, the jewellery should be stored in a soft pouch separate from each other or in a fabric-lined case with a compartment/divider to prevent damage from metal-to-stone contact.
The gold plating on jewellery can wear down over time, depending on the atmospheric humidity and usage.
Silver and gold plating tarnishes when exposed to air; do store your silver jewellery in plastic ziplock bags to avoid contact with air.
