The 'New Slaves' hitmaker, whose girlfriend Kim Kardashian gave birth to their first child, daughter North West, in June, was spotted looking at diamond-encrusted jewellery for their upcoming wedding at Cartier in Beverly Hills, reported E! online.
"Kanye was looking really carefully at wedding bands, like he was making a big decision. And by big, I mean, the stuff he was looking at was the most expensive, biggest diamonds in the whole store," a source said.
The 36-year-old rapper left the store empty-handed despite handing over his credit card at the counter and it is believed he ordered a custom-made piece for the 'Keeping Up with the Kardashians' star, 32, who was married twice before.
