This is an example of the standard Diamond Circle pin for 75-year members of Tri Delta.
Members who have reached the 75th anniversary of their Initiation have the privilege of buying the pin or receiving it as a gift. Introduced in 1996, the first Diamond Circle pin was presented to past Fraternity President Mary K. Wise Jensen, Butler.
The Diamond Circle pin features a delta inlaid with a diamond supported by three deltas of gold inside a golden circle, which is surrounded by six spherical triangles.
