AI Appraisal Estimate

This is a vintage three-footed ferner bowl crafted in amethyst carnival glass, featuring the iconic 'Grape and Cable' pattern most synonymous with the Fenton Art Glass Company. The piece is characterized by its deep purple base glass color, enriched with a high-luster iridescent metallic coating that reflects a spectrum of oil-slick colors, including copper, magenta, and peacock green. The exterior is molded with high-relief decorations depicting clusters of grapes, textured serrated leaves, and winding vines (cables). The bowl stands on three distinct spatula-style feet and terminates in a decorative ruffled or scalloped rim. This specific design and form suggest production in the early 20th century, likely between 1910 and 1920, during the height of the carnival glass craze. The craftsmanship is evident in the crispness of the mold work and the evenness of the iridized finish. In terms of condition, the piece appears well-preserved with a strong, vibrant patina; however, typical of items this age, one might expect minor 'flea bites' or internal straw marks from the manufacturing process. No major cracks, chips, or significant wear to the iridescence are visible in the provided view.

I have carefully examined the provided images of this Fenton Grape and Cable Amethyst Carnival Glass Ferner. This piece remains a cornerstone of early 20th-century American pressed glass. The amethyst base glass exhibits excellent depth, and the 'Grape and Cable' mold work is remarkably crisp, indicating a relatively fresh mold at the time of pressing. The iridescence, or 'marigold' effect on amethyst, shows a desirable saturation of magenta and teal hues with minimal surface rub. Authenticity appears consistent with Fenton’s production circa 1910-1925, specifically noting the spatula-foot construction and the ruffled rim characteristic of the period. The market for carnival glass has stabilized; while no longer at its 1990s peak, high-quality amethyst pieces with strong luster continue to command steady interest from type collectors. Comparative sales for this specific form in excellent condition typically fall within the $175 to $250 range. Significant value drivers here include the integrity of the three feet and the lack of 'stilt marks' or chips on the scalloped edges. Limitations: This appraisal is based on photographic evidence only. A physical inspection is required to check for 'annealing cracks' near the feet or base, which are common in this form and would reduce value by 50%. Furthermore, while the mold and color match known Fenton signatures, a definitive authentication would require checking for the presence (or absence) of the 'F' in an oval mark (used in later reissues) and checking for the specific weight and resonance of antique glass. Provenance documentation regarding its history of ownership would further solidify its valuation.
