Birth of a Star. The Aurate x Marilyn: Birth of a Star Tennis Necklace is a modern heirloom inspired by the woman who changed the meaning of glamour forever. Designed in honor of what would have been Marilyn Monroe’s 100th birthday, this piece channels the kind of brilliance that never fades. A continuous strand of light-catching lab grown white sapphires sits at 16 inches, perfectly placed just below the collarbone. Elegant without trying too hard, it’s designed for the woman who knows exactly what she’s worth.
