Gemstone Jewellery: Gem stone hardness is based on a standard called the Mohs scale. The higher the Mohs scale number, the harder the stone is. For example Quartz (the stone that makes up sand) is rated at 7 on the Mohs scale, and that is why any gemstone with a rating of less than 7 is easily scratched because they are soft or porous gemstones (such as coral, lapis lazuli, opal, pearl, and turquoise).
Pearl, opal, emerald, turquoise, amber, coral and onyx are all examples of delicate, soft or porous gemstones. As such, silver or gold jewellery items which carry this type of gemstone should be carefully cleaned by using designated care products. Please do not use regular dips, or care kits for these stones. Harsh, abrasive cleaners will scratch these precious stones, creating flaws that remove their lustre. Even soaking in warm water can damage these gemstones, as residues left behind once the water has been absorbed build up leaving them dull and lacking their original shine. We advise against ultrasonic cleaning. For the same reason, care should also be taken to avoid contact with make-up, perfume or hairspray. Where such stones are dampened, they should always be allowed to dry completely before being stored away. We advise against wearing it when in contact with extreme temperatures and rugged services. Stones may become loose over time and we recommend periodic examinations to assess the security of settings.
Diamond, sapphire, ruby, topaz, garnet, cubic zirconia and aquamarine are all examples of hard, non-porous gemstones.
Oxidised Sterling Silver Jewellery :This must not be cleaned with a silver cream cleaner or dipped. It will lose its darker oxidised finish if it comes into contact with silver dip. Clean your silver jewellery with Town Talk Silver Polishing Cloth or wash with warm soapy water if your jewellery is suitable for this.
Marcasite Silver Jewellery : We recommend using Town Talk anti-tarnish silver polishing cloths for care of silver marcasite jewellery. Town Talk Silver Polishing Cloths are ideal for anyone who wants to keep their jewellery clean and sparkling wherever they are. A gentle rub from time to time will keep your silver looking clean and bright at all times.
Alternatively : Step 1 : Wipe marcasite jewellery gently with a soft, damp cloth. Never use hot water and avoid soaps, cleaners, silver dips or other chemicals. Although soap and other cleaners won't damage the marcasite, they may dissolve the glue that holds the setting in place.
Step 2 : Dry the jewellery carefully with a soft, absorbent cloth or Town Talk Anti-Tarnish Silver Polishing Cloths.
Step 3 : Lay the jewellery on an absorbent towel and allow it to air-dry overnight, or until you're sure the piece is completely dry.
Anodized Aluminium Jewellery : The best way to care for your anodized aluminium jewellery is to gently wipe your piece down with a very soft cloth after wear and place it in a plastic bag to reduce exposure to the elements. If this is done regularly, you should not need to thoroughly clean your piece.
Anodized jewellery requires special care because abrasives can remove the coloured oxide layer. You certainly don't want your piece scraping against hard surfaces. When cleaning, never use polishes or cloths that contain abrasives or silver polishing cloths. Do not place anodized pieces in ultrasonic cleaners. Any harsh chemicals like hairsprays, perfumes, bleach, chlorinated water and even your sweat can deteriorate the oxide layer over time, so try to avoid contact with these substances and rinse your pieces as soon as possible after exposure.
Therefore the safest method of thoroughly cleaning all anodized aluminium pieces is to bathe the piece in warm, soapy water for a few minutes. Use a mild soap such as Dawn dish soap (not a harsh detergent) to help remove any dirt and oils that have accumulated. Afterwards, rinse well and pat or air dry. Once completely dry, it is best to store the piece in a plastic bag to reduce exposure to the elements.
Bronze Jewellery : Some people like the patina that accumulates on bronze. Once formed, this layer can actually protect bronze from corrosion. If you want to keep the patina on your bronze jewellery, do not clean it with any household cleaners.
To clean bronze jewellery, please follow these steps:
First, wet a soft towel with warm water and mild soap and use this to remove dirt off your jewellery. However, do not scrub the pieces or you may damage their coloured layer.
Next, dry them by patting gently with a clean towel while applying very light pressure, as if you were cleaning your glasses. Do not scrub the jewellery as hard rubbing may damage its layer, which gives the piece its colour.
Do not leave bronze to air dry if you don’t want your jewellery to look spotted afterwards.
