WHAT IS PATINA?
Patina
The term patina is used to describe jewelry which changes color after exposure to oxygen. This change is gradual with time, and can often be used to date items. People associate the term with sterling silver jewelry, but many other metals can be affected as well as silver. Many collectors like the aged look that patina gives a piece and like to have this patina intact. Others like to have that newly purchased, polished look, so they will remove the patina with various methods of cleaning.
It is often hard to remove the patina that has built up over time. Patina does not damage an item. It is a byproduct of time and exposure to the elements. It should not be confused with verdigris or green gunk, which is a more damaging condition.
