This is an example of the standard Golden Circle pin for 50-year members of Tri Delta.
Introduced at the 1962 Convention, where it was given to the Golden Circle members in attendance, this pin was originally designed by Sarah Ida ShawBoston University for the Circle Degree of Initiation.
The Golden Circle pin features a delta in white enamel supported by three deltas of gold inside a golden circle, which is surrounded by six spherical triangles in blue enamel.
