Gold-tone class ring with red stone (not authenticated)

This is a vintage-style class ring featuring a polished, dark red synthetic stone set in an oval bezel at the center. The ring displays intricate molded detailing and black-enameled background recesses on the shoulders and bezel surround to make the raised lettering and symbols stand out. The bezel frame includes legible raised lettering appearing to spell out school-related text. The shoulders feature detailed relief work, with one side showing the numbers '23' and text reading 'TANA' and the other side displaying the text 'KNIGHTS' alongside a mascot or emblem. The metal has a warm gold-tone finish with moderate surface wear consistent with age and handling. There is no directly visible maker's mark or metal purity stamp in the provided photograph, so the material composition remains unverified. The identification rests purely on the visual characteristics of a traditional high school or college commemorative ring. The overall design suggests a mid-to-late 20th-century period piece, though the exact year of manufacture cannot be determined from the image alone.

Based on what I can see in the photograph, this appears to be a vintage-style class ring featuring a dark red synthetic stone, gold-tone finish, and detailed relief work with lettering such as 'KNIGHTS' and 'TANA'. I can't verify from a photo the actual metal composition, as there is no visible hallmark or purity stamp, and the gold-tone finish suggests it may be a base metal rather than solid gold. Physical inspection would be needed to confirm the materials and exact age. The estimated value range of $50 to $150 assumes the piece is a vintage commemorative item in wearable condition with moderate surface wear. General market demand for generic or unverified class rings is typically modest, driven primarily by nostalgic appeal or scrap value if precious metals are present. If physical testing reveals the item is a modern reproduction, replica, or made of base metal without precious content, the value would likely drop toward the lower end or be limited to costume jewelry value, roughly $15 to $30. To establish an accurate valuation and confirm authenticity, an in-person examination, hallmark verification, and possible metallurgical testing by a qualified professional would be necessary.
