Antique 1920's-30's Kappa Sigma Fraternity Guard Pin 14k Gold, Ruby, Emerald

Antique 1920's-30's Kappa Sigma Fraternity Guard Pin 14k Gold, Ruby, Emerald, seed pearls. This pin has a smaller beta theta pin connected by a chain. The main pin features a 14 karat gold base enameled with a star, skull, and swords, as well as five emeralds, 10 rubies, and 12 seed pearls (the 3 pearls on the right are faux replacement pearls). This pin is unmarked but has been acid tested and tested as 14 karat yellow gold .These guard pins were produced in either 10 karat or 14 karat yellow or white gold and I have never seen one produced in anything other than gold. Others from this time period that I have found were also unmarked. The total weight is 5.3 g, and the price is based on the scrap value of the gold, not the historical value of the object itself. Due to being priced based on scrap value, I am not looking for offers on this item, as I can scrap for asking price, but would prefer to sell as a historical piece. see pictures for measurements, condition, and weight.
