HarmonySCS Certified Harmony Recycled Metals

All Harmony recycled precious metals at Hoover & Strong including gold, platinum, palladium and silver are 100% recycled. When it is necessary to obtain recycled metal from other sources, we buy metal from other earth-friendly refineries that, like us, only use recycled metal. We require any secondary refinery to provide in writing, full disclosure of their metal sources.

Harmony Recycled Metals were originally certified by SCS Global Services in 2009. We are audited every year by SCS, and have received the renewal certficates for 100% Recycled Precious Metals every year since then.*

SCS Certification

Beginning in April 2012, SCS Global Services, a globally-recognized independent third party sustainability expert, certified us as a "Responsible Source" refiner. We continue to receive the renewal certifications for Responsible Source every year.

Harmony Diamonds

Search our database of over 8,000 certified loose diamonds, all of which are conflict-free and come from sources that are full participants in the Kimberley Process Certification System. This process, created to eliminate the flow of  "conflict or blood diamonds", requires participating countries to tightly control the import and export of rough diamonds and to establish control systems over their private sectors that trade in rough diamonds.

Our customers now have the option of searching our Harmony Diamonds collection which includes recycled diamonds AND Canadian diamonds. Our recycled diamonds are the ultimate eco-friendly diamonds, as they do not cause destruction to our Earth and the Canadian diamonds are mined, cut and polished in the Canadian North and are subject to strict standards set out by the Government of the Northwest Territories that protect the Arctic environment and the mine workers as well.

We also offer diamond melee that is 100% recycled. This saves on energy and water usage as well as emissions and has a lower impact on the environment to name a few benefits. The melee is painstakingly cleaned, sorted and graded in house to insure the quality and value is everything you come to expect from Hoover & Strong. View our inventory of Harmony Diamonds and match them up with any of our Harmony precious metal products to create beautiful, eco-friendly jewelry for your customers.

Our "GREEN" Processes

Hoover & Strong is fully committed to recycling and protecting the environment in every way possible. Our facility is operated at the highest standards in the industry and we expect no less from our vendors and suppliers. Throughout the Hoover & Strong factory, we’ve instituted internal processes that re-use materials and conserve energy.

RefineryIn the Mill and Jewelry Division: 

  • All clean manufacturing scrap from our operations is re-melted.
  • Floor sweeps, sink sludge and mixed scrap are all refined.
  • Cooling water from casting and melting is re-circulated within the plant.
  • All copper and brass is recycled from the tool and die department.

In the Refining Division: 

  • A newly developed gold refining process reduces the quantity of waste products generated per ounce recovered by 75%.
  • A newly developed platinum and palladium refining process reduces the quantity of waste products generated per ounce recovered by 60%.
  • All furnace and chemical exhaust fumes are processed through a scrubber system that removes all harmful particulates, cleaning the air before it is released into the environment.
  • The water treatment facility removes all harmful materials from our waste water before it is evaporated. Absolutely no waste water is discharged into the environment.
  • All cooling water for our refining smelting furnaces is provided by a fully recycled, no-loss water cooling system.
