Dating to the 1980s or so, may I offer this silver pin/pendant combo in an Edwardian Revival design. Filled with cubic zirconia (CZ) man made gems the focal point is a pale, pale, pale aquamarine (appears to be genuine but could be a synthetic). The design is floral in nature with leaves. There is an overly large bale (for a thick or thin chain) at the back if wanting to wear as a necklace as well as a safety catch to keep the pinstem in place if worn as a brooch. Condition is very nice with no problems I can spot.
Metal Content: Sterling Silver with a Hallmark of 925 on the back of the piece.
Size is 1-3/4" x 1-1/2" - weight is 12.7 grams.
Final Comments: Gorgeous!
