"Do you have diamonds?" I asked with the utmost seriousness I could manage.
He nodded, "I do."
I smiled. "How big are they?"
He arched an eyebrow. "They're plaques with our Kingdom's founding history, records of every coronation, and every Monarch's personal achievements."
I covered my face and let out a groan, "Do you have, like... records of who has big diamonds?"
"How big do you need them to be?" he asked with a chuckle.
"Thirty cubic centimeters would be ideal," I replied with hope, leaning on the desk. "If not, thirty long and ten wide the smallest."
"That's too big," he shook his head. "Even the small option is bigger than anything out there."
"Okay," I sighed in defeat. "How about a diamond mine in a nearby country?"
