Platinum jewelry has always been known to be of high purity, usually 90% or higher. In the North American, as well as the European markets, the consumer has associated platinum jewelry with high quality and high value. Changing the stamping requirements to include a wide range of platinum purity with the use of base metals, or other non-platinum group metals will be confusing to the consumer and may contribute to substandard repairs or restoration in the repair shops. If there is a demand for lower purity platinum products in the jewelry industry, then new terminology should be introduced to designate the new platinum alloy mix. Platinum has an international connotation of high purity and value. The proposed changes would be confusing and offer opportunities to deceive the consumer. The proposed changes are a bad idea.
