Jewelry from the olive is protected only by natural means - with olive oil. It does not contain any other ingredients. It is necessary every few years, spread a drop of olive oil. Thus coated jewelry leave about 24 hours to absorb the oil. After that, wipe the excess oil with a dry cloth and that's all. Jewelry will take a little darker color, due to oil that protect it against dryness for centuries.
