Alloys

Recycling gold - to protect nature and the environment

The more gold we reuse, the less we have to extract from the ground.

Our precious metal alloys originate from suppliers, who produce new semi-finished products in a closed loop for jewellery manufacturing.

By recycling gold we can offer our clients semi-finished products from sustainable production and which have been manufactured in an environmentally friendly manner without using new material from mines.
