Vintage retail Antique 9k Open Domed Croissant Ring Sz 5

Product Name: Vintage retail Antique 9k Open Domed Croissant Ring Sz 5
Marked 375, SJL with Hallmarks retail. In good preowned condition. See pics for details. I am not good with Hallmarks and I make no guarantees that this is accurate but this looks like a Crown, possible a rose and an E meaning this is English Sheffield made in the 70's, possibly. The hallmarks are hard to make out. Weighs 2.3g. Item Condition: Unless otherwise stated, the items I sell are preowned. Preowned items may have fine marks and scratches.
