Marr???).  Great patina - new owner may wish to clean.  Pin back is in good working condition.  The pin bar appears to be brass.
The weight 4.69 grams.
Ring boxes and other display pieces are not included.
The
items I list are pre-owned.  Some are vintage or antique.  They may not be perfect but I will describe to the best of my ability.
Ask questions!
My sterling silver jewelry and items are pre-owned and pre-loved.  Older quality silver offers a soft patina that is warm and unique to the history of each individual piece.  There may be light surface scratches but that is normal for silver.  I do my best to describe the items.  However, I occasionally miss something.  Questions are always welcome.
I believe that all problems can be resolved if the buyer communicates with the seller.  It is EBAY's posted policy to contact the seller before leaving negative/neutral feedback.   Negative/neutral feedback neither helps nor resolves problems.  It is permanent and damages the reputation that we strive so hard to establish.
