Floyd Mayweather recently proved just how serious he was about marrying his fiance, Miss Shantel Jackson by showing off two diamond rings he purchased for her.

The boxing champ took to his Instagram page to show why diamonds are always a girl's best friend by uploading two beautiful rings and matching bracelets worn by Jackson--gifts he copped her.

In one image, Jackson is seen wearing a yellow diamond with a link bracelet.

"Ring... 25 CARAT fancy intense yellow. Bracelet... 50 CARAT fancy yellow," Mayweather captioned the photo.

In the second image, Jackson flaunts another diamond ring and bracelet with charms.

"I showed her right hand and forgot to show her left hand. Sorry ladies & gentlemen. #TMT themoneyteam.com," he wrote.

Enstars reported earlier that Mayweather announced his engagment to Jackson after he defeated Canelo Alverez on September 14. The undefeated boxer, who was named by Forbes as the Highest Paid Athlete in the World, confirmed his engagement during an interview on the Howard Stern Show later that month.

"Yeah, we still engaged. She's my better half. Miss Jackson. She's cool, she's just my better half," Mayweather said. 

Jackson isn't the only celebrity who received rings over the holidays.

Miami Heat player Dwyane Wade proposed to his actress girlfriend Gabrielle Union right before Christmas with a stunning 8.5 carat diamond ring, while Basketball Wives reality star Evelyn Lozada received a 14.5 carat ring worth $1.4 million on Christmas day.

Tamar Braxton's husband Vincent Herbert also gifted a reality star a brand new diamond ring as a sweet Christmas present.
