Italian Green Onyx Art Deco Style Mantle Clock Case, c. 1970s-80s

The valuation logic centers on the direct comparable sale of an Art Deco onyx clock case in similar condition (missing movement) that achieved $80 at Selkirk Auctioneers in 2021. This establishes the baseline for non-functional decorative clock cases in the current market. Working examples of generic Italian onyx clocks from the same period typically sell for $65-150, with branded Il Quadrifoglio pieces showing no significant premium—their glass bowls realize only $26-43, indicating weak brand recognition. The subject's value derives almost entirely from its decorative appeal as a sculptural object rather than horological function. The broader market context shows that late 20th-century Italian stone decoratives occupy the lowest tier of the clock collecting hierarchy, well below Swiss makers (Imhof, Swiza at $300-1,200) and luxury brands (Cartier, Jaeger-LeCoultre at $2,000+). Current retail asking prices for complete, working Italian onyx clocks range from $416-463, but these represent optimistic dealer pricing rather than auction realities. Given the soft market for 'brown furniture' and traditional ornaments, combined with the piece's incomplete state, the fair market value range of $50-100 reflects realistic auction expectations for a decorative stone fragment requiring restoration.
