Diamond Expert Weighs In On Kimberly Guilfoyle's Engagement Ring From Donald Trump Jr.

The List spoke exclusively to Olivia Landau, a 4th-generation diamond expert, a G.I.A. Graduate Gemologist (GG), and the founder and CEO of The Clear Cut. She examined the photos of Kimberly Guilfoyle's engagement ring and offered her professional opinion on its style and cost.

Of the huge center diamond, Landau says, "It looks like an emerald cut, perhaps around 5 carats. It looks like there may be trapezoid side stones. This is a very classic design." Indeed, it's a far more simple style than the two-stone emerald and diamond ring that Machine Gun Kelly just gave to Megan Fox. According to Brides, an emerald-cut stone is rectangular in shape, with cropped corners that give it a softer look. It also has fewer facets (angles) than a round or cushion cut, so "clarity is of the utmost importance" to ensure that it sparkles. 

Landau also estimates that, depending on its quality, Guilfoyle's ring could have cost anywhere from $65,000 to $250,000 — but knowing the Trump family, it's not likely that Don Jr. went for a bargain.
