Stone and silver devoured (5)

Ross

I believe the answer is:

agate

'stone' is the definition.
(agate is a type of stone)

'silver devoured' is the wordplay.
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'devoured' becomes 'ate' (to devour is to eat).
'ag'+'ate'='AGATE'

'and' is the link.

(Other definitions for agate that I've seen before include "Semi-precious stone" , "Variegated chalcedony" , "Quartz gem" , "Old drama critic" , "Semi-precious quartz" .)
