Gemstone and silver put away (5)
I believe the answer is:
agate
'gemstone' is the definition.
(agate is a kind of gemstone)
'silver put away' is the wordplay.
'silver' becomes 'ag' (Ag is the chemical symbol for silver).
'put away' becomes 'ate' (I've seen this in other clues).
'ag'+'ate'='AGATE'
'and' is the link.
(Other definitions for agate that I've seen before include "Precious stone" , "Hard stone with concentric bands of colour" , "marble" , "Impure form of quartz with banded chalcedony, used as a gemstone" , "Quartz gem" .)
