FAQ Bijou, metal, perle…

pearl and silver earrings by Catherine Zibo

Here is some useful basic information about the materials that I use and the nuances of the techniques.

SILVER

Sterling silver (925) is a beautiful metal composed of 92.5% pure silver and 7.5% copper. Copper helps harden the silver which is in its pure state very soft, but it is also copper that makes silver darken (tarnish) over time. It is an inevitable process and happens to all non-plated sterling silver. Cleaning silver jewelry is easy: if there is no decorative oxidation, pearl or gem decor, you can dip the jewel in special jewelry-cleaning solution, rinse and dry. You can also use old soft toothbrush and basic toothpaste, avoiding to rub on pearls, gems or decorative oxidation (this can be very slightly abrasive, so don’t use on mirror polish). And finally, the easiest of all is to use a polishing cloth that comes with your jewelry or can be purchased separately: just take it and rub over darkened or dull parts. Polish and surface of silver jewelry will inevitably lose its shine and get slightly textured, especially on rings: silver stays a soft metal that can be repolished as needed. Sometimes rings can slightly deform from active wear.

PEARLS

Pearls are an organic gemstone that I use a lot! They are rather tender due to their organic nature. Nevertheless, if they are properly cared for, they can last a lifetime and beyond. Some easy rules:

  • No purell or other antiseptic should be in contact with pearls, and no perfume sprayed on them.
  • Keep your pearl jewelry ideally in soft bags, avoiding scratching against metal parts of a jewel.
  • Don’t wear pearls to the swimming pool. Remove them before shower or bath.
  • Dyed pearls shouldn’t be stored in direct sunlight for prolonged periods of time: intense, long UV exposure can make color slightly paler.
  • Jeweller’s cement that is used to fix pearls on jewelry is sensitive to rough changes of temperature. For example, it is best to remove pearl rings before washing hands under hot water after you came home from a winter walk. The cement used in earrings that you wear in winter can also sometimes fail due to the temperature contrasts.
  • ”Pearls are the last thing you put on when you dress up, and the first thing you remove when you undress.”

Pearl bracelets and necklaces, no matter how well and tight they are strung, will loosen with wear (especially with bigger, heavier pearls). It is suggested to re-string such jewelry every 1-2 years if slight stretch troubles you. But it is not obligatory!
