Here you have a pair of Alpha Epsilon Phi pins in 10 K with seed pearls. Once I took the pictures I did re-attach the two by the small chain on the smaller one.
The pair weigh 3.5 grams. The larger one is 7/8" by 1/4" and the smaller one is 1/2" diagonally. I do not see a hallmark so the pair has been acid tested to guarantee fineness as 10 K.
