19th Century Sapphire & Rose Cut Diamond Ring

A lovely petite sapphire & diamond ring that dates to the mid 19th century.  The rose gold metal has acquired a beautiful patina over the last 150 years although it could easily be polished to a bright finish.  There are six rose cut diamonds set in silver flanking a central oval shaped natural sapphire.  The band has a knife edge detail. 

Size 6, can be sized.
