The 35-year-old "Keeping Up with the Kardashians" star showed off an enormous diamond sparkler from the 39-year-old rapper next to her 15-carat engagement ring in a Snapchat video.
E! News confirmed the new ring is from Lorraine Schwartz, who also designed Kardashian's engagement ring.
West proposed to the reality star at AT&T Park in San Francisco, Calif., in 2013.
"Kim's ring is [color grade] D -- flawless," a Lorraine Schwartz rep told E! News at the time.
"It's the best color, clarity and cut there is. There's no comparison!"
"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," the rep revealed. "He wanted the diamond to look like it was floating on air."
A source recently told Us Weekly the new, 20-carat ring is also color grade D and worth an estimated $10 million.
