As Kothari speculated to Page Six about Frankel's envy-inducing engagement ring, "If it's a real, natural diamond, I'd estimate its retail value at up to $1 million for a natural emerald-shaped diamond ring of that size." Meanwhile, Mike Fried, CEO of the Diamond Pro, says the eye-catching jewelry's value could "top $1 million" (via Fox News). Yeah, we are in shock, too.

But, Kothari noted that the ring could be "a good fake," costing around $5,000. It's worth noting many celebrities wear lab-grown stones instead of the real thing, including Bindi Irwin (via The Knot).

Meanwhile, this new ring marks a substantial upgrade from the bauble the star's first husband Jason Hoppy gave Frankel when he proposed to her in 2010 (via HuffPost). That stone was 6.5 carats — still a giant diamond, which incredibly, she later upgraded according to E! Online.
