Sigma Theta Tau Fraternity/Sorority Key Pin/Charm

This item is a small, key-shaped lapel pin or charm, likely made of gold or a gold-tone metal. Its overall size appears to be approximately 1 to 1.5 inches in length. The design is highly symbolic, featuring a circular top section with an ornate border, possibly adorned with small, dark gemstones or enamel dots that are difficult to discern precisely from the image but appear dark and possibly glittery. Within this circular part, the Greek letters 'ΣΘT' (Sigma Theta Tau) are prominently displayed, suggesting an affiliation with a sorority or fraternity, most likely Sigma Theta Tau International Honor Society of Nursing given the clear legibility of the letters. Below the letters, there is an emblem that resembles a balanced scale, a common symbol for justice, balance, or perhaps knowledge/education. A banner or scroll design is also visible behind the letters and above the scale. The circular top transitions into a stem or key shaft that terminates in a pointed key bit. At the very top, there is a small circular bail or loop, indicating it could function as a charm or be attached to a chain. The metal exhibits a warm, golden hue, typical of gold. There are no obvious signs of significant damage such as dents or deep scratches, but a slight patina or surface wear consistent with age and handling is visible on the raised areas. The craftsmanship appears to be of good quality, with clear detailing in the letters and symbols, suggesting a professional manufacturing process for regalia. The style is indicative of early to mid-20th-century collegiate or organizational jewelry.
