If you like bugs, this little fellow is charming.
Designed sometime before 1939 (based on the signature) by Alfred Philippe who was the chief designer for Trifari.
It has a most unusual glass stone for its body....it's almost cylindrical and is a very deep blue. The stone sits atop the rhodium plated metal frame that is accented with clear crystals and has 2 tiny emerald green stones for eyes. The clip is a little loose but it holds and the plating is in excellent condition. The crystals still look bright and sparkly with only a few of them starting to darken with age. It measures 1.5" x 1.25" and is signed "KTF".
