Blue design of quartz panel, oddly chipped (5)
I believe the answer is:
azure
'blue' is the definition.
(azure is a kind of blue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for azure that I've seen before include "tone perhaps" , "A bright sky-blue" , "Delicate blue" , "Deep blue colour" , "Light blue" .)
