Sampling by Sworn-in essayers
|
Our chemists certify the purity of our precious metals alloys basing on their knowledge. The exact content of gold is ascertained by processing the alloys in fire and a nitric acid bath. The label consigned by our sworn-in assayers, on oath according to Swiss legislation, is strictly governed by the federal law on the control of precious metals. This law is one of the most stringent in the world and formalises the relationship of trust with our clients. >>> |
