What is My Favorite Piece?

My Favorite Piece is a jewellery brand from Finland, founded by Jonna Tiitinen. She developed the idea in 2013 and set up the company a year later, in 2014, with the aim of giving discarded materials a second life as jewellery.

Products and positioning

Earrings are the heart of the range. The very first product was a pair of painted nutshell earrings, and pistachio shells remain a signature material. Current collections also use:

  • Leather waste
  • Plastic from bottles
  • Other materials that would otherwise be thrown away

The brand positions itself on upcycling and ethical production in Finland, turning waste streams into lightweight, colourful statement pieces.

Why it matters

My Favorite Piece is a small but clear example of circular design in accessories. By building its identity around unusual waste materials rather than precious metals, it shows how sustainability can drive both the product story and the look of a jewellery brand.
