SCS Certification


In 2009, Hoover & Strong became the first jewelry manufacturer to be independently certified by SCS Global Services for the recycled content of its Harmony Recycled Precious Metal products. SCS Global Services is a globally-recognized independent third-party certifier and sustainability expert.

Today, Hoover & Strong receives the Responsible Source Certification from SCS Global Services every year. Part of this certification confirms that our range of Harmony recycled precious metal products are manufactured using 100% recycled precious metals.
