Value Breakdown

• The "3" with End Cap" Description: This style of jewelry is traditionally called a stickpin or tie pin. The long metal pin stem (measuring roughly 3 inches long) typically terminates in a protective, removable slide-on end cap (also known as a clutch, pin guard, or safety cap) to prevent the sharp tip from poking through clothing or skin.

• Material & Maker Value: Because the piece is marked STERLING with a gold-wash finish, it holds intrinsic silver weight value. The maker's mark cartouche ("AMSUA" or a similar stylized mid-century stamp) places it into the collectable mid-century costume jewelry category.

• Gemstone Factor: The faceted green setting appears to be an emerald-tone glass rhinestone paste accent. If independent testing ever verifies the green stone as a genuine natural emerald, the value would increase significantly depending on the carat quality.
