So Kanye West did a very good job when he designed the giant 15-carat sparkler from Lorraine Schwartz to propose to Kim Kardashian with at AT&T Park baseball park in San Francisco on Monday night.

But how does Kim's new super bling, thought to be worth upwards of $1.6 million, size up to the giant jewel.

 Kim Kardashian holds up her new 15-carat engagement ring from fiance Kanye West after the pair got engaged on Monday night.

Fashion designer Kanye was involved in the entire creative process of the reality star's new rock, and when it came to choosing someone to collaborate with he knew exactly who to turn to - Kim's favourite jewellery designer and close friend, Schwartz.

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...We wish you goo luck KW!
