Inset: Dillon Buss/instagram The 27-year-old actress (who is the youngest daughter of Demi Moore and Bruce Willis) announced her engagement on Instagram on May 4, sharing shots of the magical moment he got down on one knee and of her stunning diamond sparkler. Since she said her new fiancé Dillon Buss is "the most understanding precious human noodle" he knew she "had to be in the drivers seat with this one" and sourced and designed her own ring. She started by finding a gemstone specialist Jogani to help track down the perfect stone and met "another magical friend," jeweler Karina Noel to design it. "After much deliberation we decided on this 1910s elongated asscher cut forged in a riverbed," the star said. "I am over the moon." 06 of 06 Bethenny Frankel & Paul Bernon MEGA PEOPLE confirmed on March 23 that the former Real Housewives of New York City star got engaged to boyfriend Paul Bernon after finalizing her contentious divorce from Jason Hoppy — and she has some massive bling to show for it. A few days prior, Frankel was photographed wearing an emerald-cut diamond ring on her left hand during a beach day in Florida. Diamond expert Mike Fried, CEO of The Diamond Pro, told PEOPLE that Frankel's engagement ring looks to be a 15-carat plus emerald cut center stone flanked by trapezoid side stones. "The value should definitely top $1 million," Fried said in March. "With its stunning size and exquisite style, Bethenny's ring is a nod to her relationship with Paul Bernon and their future together."
