CERTIFICATION FOR NICKEL RELEASE

The law 94/27/CE WAS issued to limit nickel content in jewellery, as everyone knows
 
It was settled that a white gold object can not release more than 0.5 µg/cm²/week.
 
The law came into force after all the tests were approved by CEN (European Committee for Standardization) with the two following rules: EN1810 and EN1811.
 
The test provides for a solution (called "artificial sweat"), in which 1 cm² of white gold must be left for a week. After this time, the solution is analyzed with an atomic absorption spectrophotometer.
 
The results of these tests are available for our customers. The certificates show that our alloys observe the release limit.
 
Well-known Institutes of research made these tests, as we think that it is important to have an official certificate issued by an external impartial Institute. Besides, the instrument for this test (the spectrophotometer) is very complex and expensive, but certainly more reliable than spectrometers used in small laboratories. The results of these tests show that our alloys are lawful as they release fewer nickel than the limit of the law.
 
Our customers can be assured that they have to change nothing in their fittings, as they can choose between the above mentioned alloys and nickel-free alloy with Palladium. About our alloys in 9 -14 kt, it is sure that they are lawful in higher shares too. The results of the test are at our customers disposal.
 
The rule provides for a corrosion test too, but only for covered objects. "Covered objects" are all metallic elements which are in permanent contact with skin, such as pins, clasps, zips. They must have a nickel-free cover which guarantees the right release for two years. We did not make this test on our alloys, simply because they are not suitable to cover objects. It is a needful statement, to complete this declaration.
 
We point a last consideration to our customers. The objects we subjected to the tests were clean and polished, they had not been casted with scraps, and they had been cut in a suitable shape to calculate their exact surface. We do not undertake any responsibility for objects that are casted with scraps, to which nickel is added, and which are plated with any other material.
 
We are available to make the same tests on our customers objects, at a small charge.
