As one of Australia's wealthiest heiresses, Francesca Packer is known for her glamorous sense of style.

And the 27-year-old is set to dazzle in a Bulgari high sapphire necklace at the Gold Dinner in Sydney on Wednesday night. 

Francesca previewed the look on Instagram by sharing a photo of her décolletage to her 307,000 followers.

According to Bulgari, 'the wondrous Sapphire Lace necklace is the result of the artisan's ability to flawlessly balance the volume and exceptional weight of the central sapphire with the sinuous diamond texture'. 

Over 600 of Sydney's leading philanthropists and agen slot online VIPs will gather to celebrate the landmark 25th anniversary of the legendary Gold Dinner on Wednesday.

The event has raised over $30million for sick kids over the last 25 years and is the largest fundraiser in Australia. 

In addition to Francesca, Ian Thorpe, Georgia Fowler, and chicken heiress Jessica Ingham are set to attend.

Francesca split from her personal trainer boyfriend Adam Cooper in August last year.

The billionaire socialite, who lives in a $16million penthouse in Darlinghurst, had confirmed the pair were dating in December 2020, telling the Daily Telegraph: 'Adam is a great guy.

We've been dating for a while.' 

However, they broke things off just seven months later.

'It was great for a while, but they had very different lifestyles. In the end, it just didn't work out,' a source told Daily Mail Australia in August 2021.

The heiress' previous boyfriends include Van Hoorn guitarist Joshua Mullane and Melbourne property developer Kelli Holland.

She also reportedly dated Sam Zacharia, the personal trainer son of celebrity plastic surgeon Dr Michael Zacharia, in 2020.

Francesca is the granddaughter of the late Kerry Packer and daughter of Gretel Packer and her ex-husband Nick Barham.

Her uncle is casino mogul James Packer.
