Gertrude Zachary Jewelry is a jewelry store located in Albuquerque.

At a baby shower, Skyler White was given a baby tiara as a gift from her sister Marie Schrader. When Skyler attempted to return it, she was briefly detained the the store for the theft of the tiara (actually committed by Marie). Skyler estimates that the Gertrude Zachary's tiara must have cost five or six hundred dollars. After threatening to call the local TV station, Skyler fakes labor pains and the frightened store owner lets her leave ("A No-Rough-Stuff-Type Deal").
