Jewellery cleaning

Jewelry with gemstones such as diamonds or sapphires can be cleaned at home as well using mild soap and warm water.

Keeping your jewelry clean gives the gemstone(s) a good shiny appearance by removing dirt and grease (among others) from loosening them.

[1] A jeweler may provide their customers with sudsy ammonia cleaning kits, while another may sell small ultrasonic cleaners.

They use ultrasound waves and chemicals combined to create bubbles that "cling" to the foreign particles such as dirt, oil, and unknown substances.

[citation needed] Historically, some jewelers' diamonds were mis-graded due to smudges on the girdle, or dye on the culet.
