Inset: Jon Kopaloff/FilmMagic Tallulah Willis had a big hand in selecting a diamond and designing her engagement ring from fiancé Dillon Buss. After announcing the exciting news of her engagement to the film director, Willis, 27, shared the story behind her sentimental sparkler. "Still processing / overwhelmed with the love sent to my and my freckled mans — we are so grateful to all that witness our story's unfolding," said the actress, who is the youngest daughter of Demi Moore and Bruce Willis. She started by finding a gemstone specialist to help track down the perfect stone for her ring. "I found Anup, @crazygemhunter my new forever friend a few months ago while furiously trying to decode the world of diamonds. My fiancé (!!!) is the most understanding precious human noodle and when we began talking about this seriously I told him due to my lowkey (highkey lol) obsessive, perfectionist, micro lens way of viewing special things in my life I knew I had to be in the drivers seat with this one. And of course Dillon understood - because that's Dillon. 😩," Willis explained. dillon buss/ instagram Join PEOPLE starting on May 19 for an exclusive shopping event with special deals, live tutorials and more from COVERGIRL and Sally Hansen.

They worked together and "scoured the world" for the right diamond. "No stone left unexamined," Wilis said. Finally, she found the right one. "After much deliberation we decided on this 1910s elongated asscher cut forged in a riverbed," the star said. tallulah willis/instagram. Inset: Dillon Buss/instagram "Once we had the stone, Karina and I went to town and after multiple revisions and stressed texts that it needed to feel like it was on a delicaté finger of a resident of Rivendell / Ancient other worldly aliens (Karina — thank you for putting up with my late night FaceTimes and manic sketches 🤦🏼)," Willis continued. "This is the final result! Group effort, so much love, and a lot of patience for a loony toons girl, I am over the moon."
