This solution of soap and water can also be used on gold and silver. Take care to avoid using cleaning powder without any whitening chemicals, as they will affect the color of gold in particular. Check if the powder has any chlorine in it as well, as it would affect the finish of silver jewelry too.
One other rule in cleaning jewelry is to proceed with caution. If you aren't sure about the chemical content of the soap you're using, try applying it on a less conspicuous section of your jewelry first. Oftentimes chemical reactions occur right away, so you should see if the washing powder has any effect on the metals which comprise of your jewelry.
Proceeding with caution also means that you don't want to go ahead and start with literal scrubbing. If you can simply wipe off dirt from your jewelry, stick to just wiping it. Once you finish cleaning your jewelry, make sure it's dry before you store it. Keep jewelry in dry, cool and closed containers. Heat and exposure to the sun can damage your jewelry significantly.
Mother of pearl
Mother of pearl is the iridescent substance called nacre, found on the inside of some mollusks. The word nacre comes from the Arab word naqqarah which means shell. It has been used for ornament, decoration and jewelry since 3000 B.C.E. Tombs have been discovered on the sites of ancient Mesopotamia in the Middle East that contained items made of mother of pearl. In some ancient cultures it was valued more than pearls. Before the 19th century, Japanese shell divers would discard any pearls found in the oysters they got, and keep the shell.
Ancient China also used mother of pearl for decorative inlay for various objects and jewelry. The Chinese powdered it and used it in medicines and prescribed it to lower blood pressure, as a cure for dizziness and as a heart medication. Native populations of South and North America also used mother of pearl for decoration and medicine.
the main source of mother of pearl
In the Middle Ages in Europe, the main source of mother of pearl was the Persian Gulf. By the 16th century, this source had been depleted due to the huge demand. New sources were found in the Pacific. Areas in the Pacific such as The Solomon Islands and Tahiti were then plundered of their supply of nacre producing mollusks until the late 1880's when France gained control of Tahiti and restricted it. By the early 20th century the area was no longer a source of nacre.
