Caring for your jewelry
Most gemstone jewelry is fairly durable, but some care does need to be taken.
Remove jewelry before doing any housework - household cleaners are corrosive and may permanently damage your gems;
Remove jewelry before doing any manual labor; or work requiring hands to be immersed in water.
Remove jewelry before swimming or showering - chlorine, some soaps and just immersing in water, may cause damage to your gemstones or their settings;
Remove jewelry before sleeping - tossing and turning in your sleep puts excess strain on your jewelry, causing it to become loose or even break;
Only put on your jewelry after perfume and/or hair care products have dried - these may cause a breakdown of the stones;
Store in a dark place, out of direct sunlight, in a pouch, ziplock bag, or jewelry box - sunlight may cause fading of stones and the humidity in the air can cause tarnishing to silver.
General Cleaning
Silver can tarnish quite easily, leaving it looking black and dirty. To ensure that your silver is kept shiny it can be polished gently with a jewelery cloth, or you can use a standard silver polish.
Copper is likely to develop a distinctive patina. Patina is not a "defect", it is a natural by-product. If you do not like the patina effect, you can clean copper goods using standard copper polish.
Take care using polishes and tarnish removers around your gemstones, as these can cause your gemstones to become dull and fade.
