About jewelry care and the different materials
Tin
Good news first: tin doesn't tarnish, so you'll never need polishes or silver dips. A quick wipe with a soft, dry cloth is all it takes to keep your piece bright.
Tin is a softer metal than silver or brass, so it's happiest when handled gently. Avoid bending or squeezing it, store it flat in a pouch or lined box away from harder jewelry, and take it off before swimming or showering.
Handled kindly, it will stay lovely for years.
Silver
Silver will tarnish over time. That's just the metal meeting air, and it's easily undone. A few passes with a silver polishing cloth brings the shine right back.
Silver loves being worn, so wear it often. Put it on after perfume and lotion, take it off before swimming or showering, and store it in a sealed pouch when it's resting.
Cared for simply, it will stay bright for years.
Bronze
Bronze darkens as it ages, deepening into a warm patina. Many people love that look, but if you prefer it bright, a gentle polish with a soft cloth will lift the colour back.
Keep bronze dry and away from lotions and perfume, and take it off before swimming or showering. Store it in a sealed pouch so it darkens slowly and evenly.
Whether you polish it or let it age, it will only look better with wearing.
Gold plated silver
The gold layer is thin, so the aim is simply to keep it intact. Wipe your piece with a soft, dry cloth after wearing and skip polishes, silver dips, and anything abrasive, as these wear the plating away.
Put it on after perfume, lotion, and hairspray, take it off before swimming, showering, or exercising, and store it flat in a pouch on its own so it doesn't rub against other jewelry.
Treated gently, the gold will stay rich and even for a long time.
