A 15.1-carat fancy vivid blue diamond is projected to be auctioned for a whopping $48 million — the highest estimate ever for a blue diamond.

The gemstone — known as the De Beers Cullinan Blue — will be the largest fancy vivid blue diamond to appear in an auction when it is offered up at Sotheby’s Hong Kong. 

The jewel was first discovered in April 2021 at the South African Cullinan mine, which, according to Sotheby’s, is one of the very few places in the world to discover rare blue gems.

“Blue diamonds of any kind are rare on the market, but this is the rarest of the rare; nothing of remotely similar caliber has appeared at auction in recent years,” said Chairman of Sotheby’s Asia Patti Wong.

The chunk of stone was originally cut from a 39.34-carat rough piece from the mine, which was purchased from De Beers in 2008.

The mine is also the source of the largest rough gem diamond ever discovered. In 1905, the hefty 3,106 carat rock was cut to create two of the British Crown Jewels.

The San Francisco 49ers clinched a Super Bowl berth with an improbable 34-31 win against the Detroit Lions in the NFC Championship Game.

The Niners rallied back from a 24-7 halftime deficit by outscoring the Lions, 27-10 in the second half, which included 17 consecutive points in the third quarter. Running back Christian McCaffrey recorded 132 all-purpose yards (90 rushing, 42 receiving) and two touchdowns.

Quarterback Brock Purdy threw for 267 yards, one touchdown and one interception on 20 of 31 passing, while also recording 48 yards on five rushing attempts.

The Niners will face the Kansas City Chiefs in Super Bowl LVIII, which will be a rematch of San Francisco’s last Super Bowl appearance in 2020. The Chiefs defeated the Baltimore Ravens, 17-10, in the AFC Championship Game hours earlier.

Seven-time Super Bowl champion Tom Brady praised Kansas City Chiefs quarterback Patrick Mahomes and tight end Travis Kelce after the duo broke his and longtime New England Patriots and Tampa Bay Buccaneers teammate Rob Gronkowski’s record.

Mahomes and Kelce connected twice on touchdowns during the Chiefs’ 27-24 AFC Divisional Round win against the Buffalo Bills for their 15th and 16th playoff touchdowns as a duo, which tied, then surpassed the previous record held by Brady and Gronkowski.

“BEASTS. When you one up Gronk you’re doing something right,” Brady wrote on his X account in response to Bleacher Report‘s post announcing the record-breaking feat.

Brady and Gronkowski initially surpassed the previous record of 12 set by San Francisco 49ers legends Joe Montana and Jerry Rice during their Super Bowl LV against Mahomes, Kelce and the Chiefs.

Mahomes finished Sunday’s game with 215 yards on 17 of 23 passing, while Kelce recorded five receptions for 75 yards. The Chiefs eliminated the Bills from the playoffs for the third time since 2020 and clinched their sixth consecutive AFC Championship Game appearance with Sunday’s win.
