Last we saw Edward and Bella at the end of The Twilight Saga: New Moon, our favorite brooding vampire had just popped the question to his mortal lady love. But the antique engagement ring that writer Stephenie Meyer describes as a delicate piece with an oval face “set with slanting rows of glittering round stones” doesn’t appear until The Twilight Saga: Eclipse, so we talked to the prop team to get all the details. To bring Meyer’s vision to life, prop master Grant Swain started by researching engagement rings from the Victorian era, called in several samples and enlisted four different jewelers to create prototypes of the bauble. But Meyer wasn’t satisfied with any of the options, so she drew a rough sketch herself and Swain sent it to Portland-based jeweler Rick Thurber, who’d created the Cullen family crest jewelry worn by Edward and his clan. Thurber mocked up a computerized 3-D drawing of his vision and sent it to Swain and Meyer for approval. Once he’d been given the go-ahead, Thurber used the illustration to laser cut a wax model, cast the band and setting and set the face with delicate pave diamonds (cubic zirconians were preferred but there wasn’t enough time to order them!). The ring was then rushed from Portland to the Vancouver set of Eclipse, arriving just hours before filming began on the pivotal scene. Talk about a ring with history!
