All our casting grain is made of gold, silver, and alloys that are 100% post consumer recycled. This means that precious metals are salvaged from old jewelry, and scrap gold. Alloys are repurposed from electronics, catalytic converters, and other industrial byproducts. The result is gold and silver on par with newly mined ore without the negative environmental consequences. All water used in the refining process is reused, and all trace metals left over are refined and recycled. Even the wax used in the molding and casting process is reused, something proprietary to our facility and its jewelers. These processes make each piece uniquely ethical and environmentally conscious. These materials and their processes named above have been independently audited and certified by the SRSP (Signet Responsible Sourcing) and The RJC (Responsible Jewellery Council). These practices also meet and in many cases exceed all EPA (Environmental Protection Agency) and OSHA (Occupational Safety and Health Administration) guidelines and regulations for a safe and healthy working environment.
