Jewellery Safety: Nickel Free Earrings
The requirements on nickel, lead and cadmium in jewellery, and why this is controlled
This guidance is for England, Scotland & Wales
Nickel, lead and cadmium in jewellery are covered by legislation. Products that come into direct and prolonged contact with the skin (for example, earrings, wristwatches, rivets and zips) must not release nickel more quickly than a specific rate.
There are additional specific rules for post assemblies for use in piercings, and some lower tolerances for products with just a nickel coating. Cadmium and lead are toxic and are therefore also subject to restrictions.
If you are not the manufacturer or importer you should check with your supplier that the products comply with the Regulations.
EU Regulation (EC) No 1907/2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulates the use of nickel, lead and cadmium.
Anyone who supplies products intended to come into direct and prolonged contact with the skin, and that may contain nickel or its compounds, lead or cadmium, will be affected by the Regulations. Examples are as follows:
- earrings and other body piercing items
- necklaces, bracelets, chains, anklets and finger rings
- wristwatch cases, watch straps and tighteners
Nickel, lead & cadmium
Nickel is one of the most abundant metallic elements, likely to be found in most metals in trace quantities, including coins.
Lead is a heavy metal that has often been used in jewellery, to make the article heavier, brighten colours, and to stabilise or soften plastic. But lead is a toxic metal, which doesn't break down in the environment and accumulates in the human body.
Cadmium is also a heavy metal that has been used for over a century in both fashion and fine jewellery products. Small amounts of cadmium may be added to alloys used to make jewellery in order to impart specific technical and functional attributes to the metals. It may be present in jewellery as part of the metal alloy, solder or gold coating for electroforming / electroplating, or as a pigment or stabiliser in non-metal components.
However, cadmium has also been recognised as a toxin and carcinogen that is harmful when ingested or inhaled.
Nickel in products
PRODUCTS FOR USE IN PIERCINGS ('POST ASSEMBLIES')
Any post assembly for use in piercings must have a rate of nickel release less than 0.2 micrograms per square centimetre, per week. The post assembly is the part of the product designed for insertion into the wound caused by piercing, plus any faces that hold the piece in and against the wound (such as the ball or butterfly).
As well as the specific rule for post assemblies for use in piercings, all products that come into direct and prolonged contact with the skin must have a rate of nickel release less than or equal to 0.5 micrograms per square centimetre, per week. In other words, it is prohibited to supply the product if the rate of release is greater than 0.5 micrograms per square centimetre, per week. 'Direct and prolonged contact' means touching the skin under normal use for continuous periods of time.
A product may contain nickel in higher concentrations; however, this only applies where a product has a coating and the coating is sufficient to ensure that the rate of nickel released from parts in direct and prolonged contact with the skin is less than 0.5 micrograms per square centimetre, per week, for a minimum period of two years' normal use.
When testing for nickel migration, laboratories may make an allowance for uncertainty in the results using the prescribed test methods, as outlined in European Standard BS EN 1811: Reference test method for release of nickel from all post assemblies which are inserted into pierced parts of the human body and articles intended to come into direct and prolonged contact with the skin.
Lead in products
Jewellery must not be supplied, or lead used in any individual part of jewellery articles, if the concentration of lead is equal to or greater than 0.05% by weight.
This includes jewellery and imitation jewellery articles and hair accessories, such as:
- bracelets, necklaces and rings
- piercing jewellery
- wristwatches and wristwear
- brooches and cufflinks
There are some exemptions to this, such as the use of crystal lead glass in jewellery.
Cadmium in products
The Regulations restrict cadmium content in jewellery to 0.01% (100 mg/kg) by weight of metal and this applies to:
- metal beads and other metal jewellery (that is, bracelets, necklaces, rings, piercing jewellery, wristwatches, wristwear, brooches, cufflinks)
- components, metal parts of jewellery and imitation jewellery articles
- hair accessories
For products sold second-hand, the General Product Safety Regulations 2005 apply. These require goods supplied to be safe.
