Bachelor diamond ring from Zach Shallcross trends now

Zach Shallcross proposed to Kaitlyn 'Kaity' Biggar during the season finale of The Bachelor that aired on Monday on ABC.

And he did so with a large diamond ring from jeweler Neil Lane.

The rock was so big it sparkled on camera when they were hugging on the beach in Thailand. 

The 26-year-old Orange County, California native hand picked the ring himself.

It is more than three carats and has a hefty weight as it is set in platinum, according to People. 

'Kaity, will you marry me?,'  asked Zach, who was dubbed the 'boring Bachelor' at the start of his season. 'Absolutely,' Kaity answered before they started kissing on a beach in Thailand.

'We're engaged!' Kaity yelled as she held up her huge sparkling engagement ring by Lane.

The ring is a showstopper. 

'It's like a huge disco ball,' Biggar told People.

It has a center oval-cut diamond placed on a three-sided diamond band and surrounded by a halo of round-cut diamonds, per the site.

The custom Neil Lane ring, is made of platinum, also features a gallery set with over 150 smaller diamonds, which brings the piece to nearly 3.10 carats, People added.

'It's heavy, huh?' Shallcross said to Biggar.

Lane said, 'When it came time to choose the ring it was the oval with all its brilliance and sparkle that Zach felt best represented Kaity. It was a thrill to see her reaction. I wish them a lifetime of joy and happiness.'

'Look at that rock!,' Zach said.

'It's very nice,' Kaity said.

Zach then offered Kaity his final rose and she accepted.

They drank champagne on the beach and boarded a small boat that carried them away.

There was also some sadness on the show.

Zach sent home Gabriella 'Gabi' Elnicki, 25, after breaking his no-sex rule with her in the Fantasy Suite. 

The show then proceeded with Ariel Frenkel, 28, of New York City, meeting Zach live in front of a studio audience after she was eliminated on last week's episode.

Zach confessed to Gabi and Kaity that he broke his vow of not having sex in the Fantasy Suite, but did not tell Ariel who found out by watching on TV.

'I'm really hurt. It really hurts to find everything out on TV, when everyone else does, with a partner that you have shared so many intimate moments with. I was really disappointed in the way the whole week was handled. I was disappointed in the way that I was left completely not knowing anything from Zach,' Ariel said.

Zach apologized to Ariel and said there was no excuse for his behavior.

The finale then returned to pre-recorded events in Thailand where Zach reunited with his family, including his parents Megan and Chapman and sisters Payton and Sammy.

Kaity met Zach's family first and gushed about him to Megan.

'He's an amazing guy, truly. Like, truly. I feel so safe, so secure with him. He is there for me. And I haven't had that. And, like, you know, we haven't had, like, the smoothest ride. I mean, there is another woman here, too,' Kaity said as she got emotional.

Zach's sisters asked if she was prepared in case things went 'sour'.

't would be heartbreaking and it would very tough, obviously. I honestly didn't think that I could find somebody so amazing. I just want him to be happy and follow his heart,' Kaity said.

'Awww,' Payton said.

Kaity told Chapman that she was 'very
