Pharrell Williams will only wear jewellery with healing properties.

The Happy singer now shuns expensive, oversized bling for precious stones possessing medicinal values which he feels can improve his quality of life.

He said, “For ages, I got it wrong. I was competing with others because I wanted to draw attention to myself.

“But in the same way as I realised I wanted to put peaceful things in my music, I decided I should only be wearing jewellery with medicinal and holistic properties.”

“For example, I wear yellow diamonds or emeralds because those stones have healing qualities, as well as soft water pearls,” added Pharrell. “I don’t love jewels for what they represent. I love them for what they express, because they’re who I am inside.”

The star once had a very different taste in accessories.

Pharrell memorably teamed up with luxury fashion house Louis Vuitton in 2008 for a line of fine bling called Blason, which ranged in price from $2,000 to a whopping $621,000.
