Switzerland's Chopard mixed gemstones and precious metals with less noble metals such as aluminium that can be dyed and worked into lightweight, ornate structures.

"It allows us to produce very creative pieces," said Celine Wackie-Eysten, director of communications at the brand.

Chopard's latest "high jewellery" display - where pieces can fetch more than 1 million euros, though prices are not disclosed - included a necklace in red aluminium adorned with rubies and shaped into pompoms.

Another highlight was a large cameo pendant mounted onto an necklace made out of iridescent heron and pheasant feathers.
