A dress fit for a diva! Mariah Carey gave Us the first glimpse of what she might wear at her wedding in a new trailer for her upcoming E! docuseries, Mariah’s World.

In the footage, the “Butterfly” singer, who got engaged to billionaire businessman James Packer in January, teases fans with a seconds-long glimpse of her in a wedding dress. The gown is a plunging, white, beaded creation that shows off her décolletage and tiny waist. For full effect, Carey tries it on with an ethereal, lace-trimmed veil. The show, which debuts on December 4, also follows Carey through other steps of planning her wedding, as she performs for her Las Vegas residency and tours in Europe.

Though this specific design might not be the one she ultimately chooses for her big day, we do know at least one accessory she’ll be wearing: her massive diamond engagement ring. The gigantic sparkler features a whopping 35-carat, emerald-cut center stone. The “Honey” singer’s eye-popping middle gem is flanked by two tapered baguette diamonds and finished in a platinum setting.

“I took the standards superhigh, and I wanted to create a ring that could not be measured up to,” Carey’s go-to jeweler and friend Wilfredo Rosado told Vogue of his design. “The stone is so large, but we were able to create a beautiful balance with the overall simplicity of the design. It was about mixing simplicity with volume, which is very difficult to do.”

Carey’s stone is nearly twice the size of Beyoncé’s 18-carat diamond and dwarfs Kim Kardashian’s 15-carat stunner and Jennifer Aniston’s 10-carat ring.

Though Carey’s wedding to Packer won’t be her first (Carey was previously married to Nick Cannon for six years, before they called it quits in 2014, and Tommy Mottola, from 1993 to 1998), Rosado wanted the ring to be a symbol of a fresh start. “We have the same taste, and when it came down to it, I really wanted to create something for her that was about new beginnings,” he explained. “But it is epic. It’s an epic ring for an epic time in her life.”
