I believe “the Lady” was a 44,472 ct Citrine cut by the Dare-Devil Faceters.
“The Dare-Devil Faceters of the Intermountain Faceter’s Guild have
used copper laps to preform all their “BIG” stones such as The Lady at
44,472 carats, Miss l Lemon Drop at 22,951 carats, Sun Princess at
14,812 carats, the Countess at 12,678 carats as well as others.”
