Aussie model Jessica Bader flashes massive diamond ring worth $100k as she announces engagement to Adam Arias

Jessica Bader has announced her engagement to longtime partner Adam Arias.

The swimwear model, 26, couldn't contain her glee when she shared footage to Instagram celebrating the milestone moment, while flashing her blinding diamond ring. 

In the clip, which appears to be taken in an old-school photo booth, the loved-up couple are seen passionately kissing while the brunette bombshell pouts up a storm and uses every opportunity known to man to flaunt her whopping sparkler. 

Jess captioned the video, '10.10 (October 10)' alongside a ring emoji.  

According to reports, the ring appears to be a three- to four-carat marquise-cut diamond.

A natural diamond could fetch between $80,000 and $100,000. 

In a separate post, the genetically blessed duo are once again smooching, this time in an outdoor rural setting.

Jess opted for a slinky white 90s style dress with spaghetti straps for the occasion, paired oddly with a cowboy hat.

Meanwhile, her man looked casual cool in an olive green tee and black pants. 

He rounded out his look with a fresh fade.  

It wasn't long before the announcement was flooded with well wishes from some of the country's most famous Insta stars.

'Congrats,' gushed Tammy Hembrow. 

'Awww, congratulations,' echoed Costeen Hatzi, the ex-girlfriend of Nick Kyrgios. 

'Screaming for you,' added Married At First Sight's Evelyn Ellis.  

Sydney influencer Bella Varelis was so overjoyed she couldn't quite summon words, and opted for a high-pitched squeal.

'EEEE,' she wrote while recovering from a well-documented leg injury. 

Influencer Sophia Begg, aka sophadopha, also shared kind words, along with Gracie Piscopo and Sasha Morpeth. 

Jess has become a wildly successful model on Instagram and is the founder of popular swimwear label Jasook Swim.
