Intriguing object (5)
I believe the answer is:
curio
'intriguing object' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for curio that I've seen before include "(Unusual) collector's item" , "odd thing" , "Object of interest because it is a rare or unusual" , "Intriguing object worth collecting" , "Something unusual, perhaps worthy of collecting" .)
