Watch: Conor MCGregor unveils brand new customized 'Proper Twelve' gold chain

Conor McGregor recently unveiled a new customized gold chain modeled on his Whiskey brand Proper Twelve. The exquisite piece of jewelry comes from The Cut Price Jewellers in Dublin and was unboxed at McGregor's Black Forge Inn.

Sharing an unboxing video along with several photos of him sporting the luxurious piece, McGregor wrote on Instagram:

"Thank you @thecutpricejewellers for my @properwhiskey chain! Wow! What a team, what a family, what a price! Cut price forever! And a huge happy birthday goes out to the best all time @samcashind in the house ❤️ @theblackforgeinn rocking!!"

The Cut Price Jewellers specialize in making customized pieces and are a preferred choice of other Irish athletes as well. They recently made a ring for undefeated Irish boxing prospect Willo Hayden that was appreciated by McGregor.

Commenting on Hayden's post about the ring, 'The Notorious' wrote:

"Ah unbelievable that is Willo! Slick!"

The Cut Price Jewellers seemingly share close ties with Conor McGregor as their Instagram page consistently promotes The Black Forge Inn.

Conor McGregor is the fastest-earning athlete of 2021, considering match time

US betting site OLBG recently determined that Conor McGregor is the fastest earning athlete of 2021 judging by the minutes spent on the field, court, or ring. The Dubliner earned a whopping $33 million for his UFC 264 loss to Dustin Poirier last year.

The match ended in five minutes after McGregor broke his leg at the end of the first round. Which means 'Notorious' earned $6,600,000 for every minute that he spent inside the octagon. This also meant that it took just nine seconds of active competition for the UFC superstar to earn a million bucks.

McGregor is followed by boxers Canelo Alvarez, Tyson Fury and Jake Paul, who are the only other combat sports stars to feature on the list.

'Saul' Alvarez took just over an hour combined to defend his titles against Billy Joe Saunders and Caleb Plant, earning $85m in the process. Meanwhile, Tyson Fury roped in $60 million for his wins over Deontay Wilder and Dillian Whyte, at just under an hour's work.
