Gemstone European delivered in ceramic vessel (7)
I believe the answer is:
peridot
'gemstone' is the definition.
(peridot is a kind of gemstone)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for peridot that I've seen before include "mineral" , "I deport (anag) - gemstone" , "Top ride (anag) - gemstone" , "olivine" , "Pale green gemstone" .)
