Kate Moss’ favourite crystals are melonite and rose quartz.

The supermodel, who is set to turn 50 in January, has ditched her hard-partying ways and home in London for a country life in the Costwolds and life as a wellness guru under her Cosmoss brand.

She told The Sunday Times about her newfound love of crystals: “Melonite is really powerful. I had a piece of it but of course I lost it. I have to get one more.”

Melonite is believed to raise stamina, longevity and overall physical wellbeing, while rose quartz represents love and compassion.

Kate also admitted in her heyday she “didn’t give a s*** about what I used" as skincare – and “never” used to wear suncream.

But her Cosmoss beauty brand now sells day and night cream (for £95), as well as procollagen oil (£105) and face cleanser (£52.)

She launched it in August last year by posting a video of herself wild swimming naked.

Kate added: “Lots of brands think about the science and the ingredients. Cosmoss has all that but what I wanted was something that was actually going to ground you and connect you to the universe.”

Part of her practice of “connection to the universe: is wild swimming in a “secret place” used by locals near her new home – a grade II listed house near Little Faringdon, west Oxfordshire.

In the mornings she also practises transcendental meditation for 10 minutes and recites affirmations.

Her favourite mantras include: “Embrace the unknown.”

She also now does ashtanga yoga or reformer Pilates, and cooks Sunday lunches for her daughter Lila, 20.

Kate also said the secret to her newfound early nights is watching ‘Frasier’ once she’s in bed, adding: “It just puts me to sleep.”
