This is a signed BSK "book piece".  The brooch is pictured in the book "Inside the Jewelry Box, Volume 2"  by Ann Mitchell Pitman on page 53, where she estimates the brooch alone to have a value of $150 - $195. 

This set has palw orange rhinestones with gold enamelled carrot top leaves.  It has a japanned finish which really makes the colors "pop".  The earrings have an open wire clip.  All pieces are in excellent vintage condition, with the exception of some japanning missing on the pin of the brooch. The rest of the japanned finish is in pristine condition.  Brooch measures 2 1/2" X 1 1/4" and the earrings are 1 3/8" X 1/2".
