Typifying the finest development of manhood, the selection of Apollo is most appropriate. The official membership badge, made of either white or Roman gold and adorned with three white pearls, is by far the most important item of TKE insignia in general use. Only this badge may be worn by undergraduate members. Jeweled badges, crown set with pearls, diamonds, rubies or emeralds, according to choice, may be worn by alumni members. Frequently the standard membership badge is used as a token of engagement.
Miniature badges are also available for mothers, sisters, or for engagement purposes.
The TKE 'badge of gold', unique in its design and distinctiveness, has never been changed since its adoption. The meaning and connotations of the badge are revealed to members during initiation. The official flower of the fraternity is the red carnation. The official flower is worn during initiations and at TKE banquets. It is also represented by the Red Carnation Ball, a banquet and dance celebrated by most TKE chapters each year.
