It’s the bling that’s blinding fans around the world.

Justin Bieber put careful thought into planning fiancée Hailey Baldwin‘s engagement ring, says the man behind the diamond, Jack Solow, a private jeweler based at New York City’s family-run jewelry store Solow & Co.

“Justin did have a hand in selecting the diamond because I sent videos to his team,” Solow tells PEOPLE. “I know him through [his manager] Scooter Braun. When it came time to find a ring, Justin asked Scooter and said, ‘I’m ready to pop the question’ and he said, ‘There is only one place to go, ask Jack.’”

Solow, who is best friends with Braun’s father, designed engagement rings for Braun and his entire family and was honored to help the singer find the perfect stone for Baldwin.

“In the end, Justin wanted something that would gracefully accentuate Hailey’s beautifully-shaped hands. We settled on an oval stone that was just exceptional in its length and grace. Look at her hands — she’s exquisite,” says the jeweler, who had a “few weeks” to make the custom diamond sparkler, which is somewhere between 6 to 10 carats.
