Vintage Larimar sterling silver brooch pin

This pen appears very old. It is vintage for sure. It has a C clasp. We have your beautiful Laramore decorating this butterfly. Guarantee 925 Sterling silver. The length approximately 1.5 inches. Looking at it now on the measuring tape it's not sitting as far up as it should. I'm giving this a 1.5 approximation in length. She is beautiful very old.
