AI Appraisal Estimate

These vintage decorative earrings are characteristic of Canadian artist Martha Sturdy's mid-to-late 20th-century design aesthetic. The earrings feature a silver-tone metal construction, likely chrome-plated or rhodium-plated brass/pewter, sculpted into a series of organic, vine-like articulated segments. Each earring is composed of three interconnected sections that provide fluid movement when worn. Along the length of the metal 'stems' are mounted spherical imitation pearls or resin beads in a lustrous white to light-grey hue, arranged in an alternating, branch-like fashion. The scale is significant, suggesting a length of approximately 4 to 5 inches, which corresponds to Sturdy's reputation for bold, architectural 'wearable art.' The metal finish appears bright with minimal surface oxidation, though light micro-scratching is visible upon close inspection. The articulation points remain intact and functional. The overall craftsmanship reflects a high-end costume jewelry standard, focusing on sculptural form and movement. Martha Sturdy's work from this era, specifically the 1980s and 1990s, is highly collectible for its modernist, oversized silhouettes and use of non-traditional industrial materials refined into high fashion accessories.

I have completed a visual assessment of these vintage Martha Sturdy silver-tone articulated vine earrings. Based on the sculptural language, oversized scale (approx. 4-5 inches), and the specific use of industrial-inspired metalwork paired with oversized resin pearls, I identify these as consistent with Sturdy’s output from the 1980s. The articulation remains fluid, and the plating shows minimal wear, though micro-scratching is present. Martha Sturdy’s larger, 'statement' pieces from this era are currently experiencing a resurgence in demand among collectors of Canadian modernist design and runway-style costume jewelry. While standard resin bangles are more common, articulated metal earrings of this complexity are scarcer. Market comparables for larger Sturdy earrings typically range from $300 to $550 depending on the complexity of the casting and the condition of the pearlized coating, which is prone to peeling. Please note that this appraisal is based on photographic evidence. A definitive authentication requires a physical inspection to verify the hallmark (typically 'STURDY' or 'MARTHA STURDY' on a soldered plaque or clip-back) and to confirm the metal composition. While the appearance is consistent with her signature use of resin and plated brass, scientific testing or firsthand handling would be necessary to rule out high-quality contemporary imitations. The absence of significant oxidation or 'green' corrosion on the joints maintains the value at the higher end of the market spectrum.
