Do

… clean your jewelry regularly with a safe cleaner for the type of metal and stones.
… store your jewelry properly to prevent damage, such as scratches, prong damage, and knots in chains.
… have your prongs checked regularly, to minimize the risk of losing a stone.
… minimize exposer to perfumes, cosmetics, hand and body lotions, and hair sprays.

Don’t

… leave batteries in watches for years – they may leak and ruin the watch.
… wear jewelry in pools or hot tubs – they may react negatively to the chemicals, causing weakening or discoloration.
… wear jewelry when using cleaning chemicals – chemical reactions can also cause weakening and change in appearance.
… sleep in your jewelry – you may bend earring posts, snap chains, get necklaces and prongs caught on clothing.
… wear loose rings – they may fall off without noticing it.
… wear your jewelry to the gym – necklaces can get caught in gym equipment and lifting weights can bend rings or hurt prongs.

Jewelry that is safe to wear in the pool:
Stainless steel – it has great corrosion resistance.
Tunsten – it has corrosion resistance and it is durable and scratch resistant.
Silicone – it is chemically stable, heat-resistant, corrosion-resistant, and non-reactive.
Titanium – it is non-reactive to chlorine.
Platinum – it is also non-reactive to chlorine.

Also:
Be mindful of wearing your jewelry and watches during activities, such as gardening and sports to prevent damage. Hollow chains are easy to break. Watch crystals can scratch or break. The gold on rings will wear down and weaken. When baking, flour can stick to rings and make them hard to clean. Silicone rings are a good option for going to the gym and with sports.
