As he carefully placed a few small stones in front of her, he said, “And these, Your Highness, we call ‘chalcedony.” Can you see the difference between these and the quartz I showed you yesterday?”

How do we know?” He paused as if he expected an answer, but then blurted out, as was his way, “Chemical analysis!” Taking her little hand in his, he pulled her away from the desk. “We’re off to the laboratory!” He said gleefully.
“Yay!” Said Pirouette, in an effort to please.
