Act as a visionary urban designer with expertise in biomimetic architecture and crystal growth technologies. Design a futuristic city where all buildings, infrastructure, and public spaces are organically grown from a unique crystalline material. Describe the city’s layout, including [NAME OF CITY], its [MAIN DISTRICTS OR NEIGHBORHOODS], and the [KEY FEATURES] that make it sustainable, efficient, and visually stunning.

Include details about the social, cultural, and economic implications of living in such a city. Highlight any innovative technologies or processes used to cultivate and maintain these crystal structures. Your design should inspire awe while remaining practical and functional for its inhabitants.
