Not only is the jewelry designer a close pal of the E! star, but Schwartz has created georgeous bling for celebs for years—including truly unique engagement sparklers for Blake Lively and Beyoncé.
Being a designer himself, it was only natural that the rapper joined in on the creative process.
"Kanye was involved in every single way. He had a vision from the beginning. He looked at a lot of stones and he wanted only the best," says a rep for Lorraine Schwartz. "He and Lorraine emailed back and forth, and stayed up nights discussing how he wanted it to be. He wanted the diamond to look like it was floating on air. Everything was his idea from beginning to end."
The result? A 15-carat diamond that is truly jaw-dropping.
"The ring is flawless. Not just internally flawless, it's flawless. It's a D-stone, the best diamond there is, type 2A," shares the rep, adding "It's a perfect cushion cut diamond."
Celebrity jewelry expert Michael O'Connor estimates the ring is worth upwards to $3 million.
Like the ring, the proposal itself was just as impressive (like we'd expect anything less from the genius Mr. West!).
Last night on the new mom's birthday at the rented-out AT&T Park in San Francisco, the Grammy winner got down on one knee and popped the question with a little help from a 50-piece orchestra and the field's jumbo screen, which read: "PLEEEASE MARRY MEEE!!!"
Of course, Kim said yes and then the duo celebrated with friends and family including the entire Kardashian clan, Rachel Roy and Joe Francis.
