Bracelet, Ring, Earrings, and Brooch set.  Goldtone with a diamond pattern. The earrings show little wear,  The bracelet and brooch have a some fine scratches.  The ring shows a fair bit of wear.  I suspect these have a very thin gold plate.  The bracelt is 2 11/16" across.  The earrings are 7/8" across.  The ring is 11/16" (size 7)    The ring, bracelet and earrings are all 5/16" wide.  The brooch is 1 7/8" x 1 1/4"

This may be Sarah Coventry jewelry but I see no markings on any of the pieces.  This were my mother's and she had some other SC pieces.
