In a pure state, gold has an excellent chemical stability therefore is resistant to corrosion and oxidation which are major concerns when a metal is used for body piercing jewelry.
But body jewelry is never made of pure gold (24K) as it’s too soft for this application.
Gold purity is measured in karats(K):
14 karat gold is 58% pure gold.
18 karat gold is 75% pure gold.
22 karat gold is 92% pure gold.
Yellow gold is made combining: Gold (Au), Copper (Cu), Silver (Ag), and Zinc (Zn)
White gold is made combining: Gold (Au), Copper (Cu), Palladium (Pd), and Zinc (Zn)
For the white gold jewerly that we sell, palladium is substituted for nickel to eliminate any possible adverse reactions to nickel.
ANATOMETAL 18K Rose Gold is Cadmium free.
The American APP (Association of Professional Piercing) states that 14k or 18k gold can be used for body jewerly. ANATOMETAL only makes their gold jewelry with 18K gold. None of their jewelry is available in 14k gold.
Anatometal 18k gold products are all made from 18k solid gold.
How to take care of your Gold Jewelry
In some cases, when people perspire, fatty acids released can cause discoloration of 14K & 18K gold, especially when exposed to warmth and air.
This can be worse in semi-tropical areas.
Discoloration can also occur if precious metal jewelry is worn in oral piercing.
This does not happen frequently.
If it does happen, the discoloration on the jewelry is only temporary and can be removed easily with a jewelers cloth or by other means of buffing.
Some antiseptics, cleaners, chlorine and improper sterilization techniques may also discolor gold.
