Origin and history

Discovered in 1803 by William Hyde Wollaston, palladium remained little-used until the 20th century, when it was adopted in the alloy and jewelry industries. Today, it is gaining popularity due to its natural white color and resistance to tarnishing, particularly in minimalist jewelry.

Uses

Palladium is particularly prized for:

  • Wedding bands : in pure white metal or combined with gold.
  • Men's rings : for its strength and natural color.
  • Settings : ideal for precious and fine stones thanks to its solidity.
  • Minimalist jewelry : highly appreciated in sleek and modern designs.

Care and storage

  • Clean with a gentle solution of warm water and soap, followed by drying with a soft cloth.
  • Store separately to avoid scratches, although palladium is more resistant than many other precious metals.
  • Have it polished occasionally by a jeweler to remove micro-scratches and maintain luster.
