Tri Delta also has various circle pins to celebrate years since the member's initiation. Introduced in 2004, the Silver Circle Pin may be worn by members who have reached the 25-year anniversary of their initiation. It features the anniversary number engraved on the stars and crescent design. The Golden Circle Pin was originally created by Sarah Ida Shaw for the Circle Degree of Initiation, but its current usage to celebrate 50 years since initiation dates to 1962. This pin consists of three deltas made of gold inside a golden circle, surrounded by six spherical triangles in blue. The Diamond Circle Pin honors members who have served for 75 years with the fraternity. While the design is alike to the Golden Circle Pin, this token features a diamond in the center. This pin was introduced in the year 1996 and the first pin was awarded to Mary K. Wise of Butler University.
