The family of Floyd Mayweather’s jeweler Aron Aranbayev, who was killed by a car in a hit-and-run accident in Queens, is offering a $25,000 reward for information about the driver who mowed him down.

Manhattan jeweler-to-the-stars Aranbayev, 40, known as “Eric,” operated jewelry store Rafaello & Co. on West 47th Street with his family. His clients also included Rick RossT.I.Busta RhymesSwizz BeatzJay ZDrake and Khloé Kardashian.

The father of four was fatally run down on his own block Sunday night. Police sources told The Post that, as the famed jeweler got out of a car at around 11:15 p.m., a man flew past him in a Dodge Magnum.

When Aranbayev yelled at him to slow down, the driver slammed on the brakes, reversed and accelerated forward into Aranbayev. He died Monday at Jamaica Hospital.

Aranbayev’s grieving cousin Gabriel Jacobs, who worked with him at Rafaello & Co., said, “We have no idea who could do this. He had no problems with anybody. Our clientele, everybody loved him, he was the life of the company.

“From what I know, he was dropped off by a friend. He was on the phone, a car was flying down the street, and he got into a verbal back-and-forth with the driver, who backed up and hit him. He fell and hit his head on the concrete.

“We, as a family, want to put together a reward with the police for the capture and the arrest of this coward,” Jacobs said. “We have the whole hip-hop and the whole entertainment world behind us. Whoever did this has to be brought to justice. If he’s a man who took away a father of four, who had a baby six months ago, an uncle, a brother, a cousin, and can still live with himself, he must be the biggest dirtbag in the world.” He’s asking any witnesses to call detectives at the 112th Precinct.

Busta Rhymes Instagrammed Wednesday, “I can’t believe they took my brother frm me and frm all of us. Eric u were truly a shining light bro . . . I love u and miss u tremendously my brother.” Swizz wrote on Instagram Tuesday, “Eric was the good guy everyone loved.”
