Crystal Hefner Marries in Cook Islands Wearing Six-Carat Vintage Mine-Cut Diamond Ring

Crystal Hefner walked down the aisle on April 2 wearing the ring that had been turning heads since Ward first slipped it on her finger: a six-carat vintage mine-cut diamond set on a whisper-thin band. The ceremony took place in Aitutaki, one of the most remote of the Cook Islands, with no guests present. Just the two of them, a local band playing a mix of Hawaiian and American songs, and a floral arch set at the edge of the beach.

The mine cut is a stone with a specific grammar. Predating the modern round brilliant by roughly a century, it carries a high crown, a small table, and a large culet that together produce chunky, candlelit flashes rather than the precise scintillation of a contemporary cut. At six carats, those characteristics are impossible to miss. The whisper-thin band is a deliberate counterpoint: with almost no metal competing for the eye, the stone holds the frame entirely. It is a pairing that trusts the vintage diamond to do its own work, and at six carats, it does.

Ward, 42, a marine biologist and founder of the eco-tour company SeeThroughSea in Kailua-Kona, Hawaii, proposed on April 25, 2025, at Hefner's Hawaii home. He had constructed a seaside deck perched above a cliffside overlooking the ocean, and led her there through a winding trail lined with handwritten notes. "It truly feels like a full-circle moment," Hefner told Us Weekly. "It was the exact spot where we'd had a quiet picnic together a year ago, a place that became 'ours.'"

Hefner wore a plunging lace gown embedded with 5,400 crystals and a long train for the ceremony. She announced the day on Instagram with characteristic directness: "Baby where the hell is my husband… probably waiting for me to walk down the aisle. Today is the day!!"

The wedding bands carried their own weight. For her ring, Hefner bypassed convention and wore a simple gold band that had belonged to her late father, Ray Harris, who had worn it on his pinky. Ward's ring was engraved on the inside with Hawaiian flowers and leaves, which he described as representing their life together and where they met.

The couple, set up by mutual friends in April 2024, chose Aitutaki specifically for its remoteness. "There are no big chain hotels," Hefner told People, "which makes it feel incredibly" personal. Hefner was previously married to Playboy founder Hugh Hefner from 2012 until his death in 2017.

The six-carat mine cut, the borrowed-from-father gold band, the cliffside deck Ward built with his own hands: each piece was chosen for what it meant rather than what it cost. The ring that started the story is the most visually arresting element, but the full picture is of a couple who treated the jewelry as narrative, not ceremony.
