AI Appraisal Estimate

This is a boat-shaped or oval centerpiece bowl crafted from thick, heavy clear lead glass or crystal, characteristic of the American Brilliant Period (ABP) style common from the late 19th through early 20th centuries. The piece features deep geometric hand-cut or pressed-molded patterns including hobstars, pinwheels, and fine diamond cross-hatching. The upper rim is finished with a sharp sawtooth or scalloped edge, while the ends of the bowl extend into integrated glass handles. It sits on a low, oval-shaped footed base which also features notched cutting around the perimeter. The glass exhibits high clarity and light refraction, typical of high lead content. In terms of condition, there are no large cracks visible, though common for this type of glass, minor flea bites or small chips may be present along the sharp points of the sawtooth rim or the geometric facets. No visible maker's marks are present in the image, but the craftsmanship reflects the intricate 'all-over' cutting style popular in American glass production between 1880 and 1915. A pink circular price tag marked '4-' is adhered to the inner side of the glass.

I have virtually examined this American Brilliant Period (ABP) style boat-shaped bowl. The piece exhibits the heavy lead content and intricate 'all-over' geometric cutting—including hobstars and diamond cross-hatching—consistent with the 'Brilliant' era (1880–1915). The clarity and refractive quality suggest a high-quality lead crystal, and the integrated handles and sawtooth rim are hallmarks of the period's craftsmanship. Based on visual inspection, the condition appears good, though the 'flea bites' common on sharp serrations typically diminish value by 10-20%. The '4-' price tag suggests a past secondary market or estate sale context. Currently, the market for ABP glass is softer than its peak in the late 1990s, with high supply and a specialized collector base. Comparables for unsigned oval bowls of this size and complexity typically realize between $100 and $250. This piece's value is bolstered by its functional size and ornate patterns, though the lack of a recognizable maker’s mark (such as Libbey or Hawkes) keeps it in a more accessible price bracket. Without a physical inspection, I cannot definitively confirm lead content via acid testing or weight-to-volume ratio. Full authentication would require a blacklight test to check for the tell-tale lime-green fluorescence of period glass, a tactile search for acid-etched marks, and a loupe examination to distinguish hand-cut facets from mold marks. Provenance documentation or original catalog identification would be necessary to attribute this to a specific prestigious glasshouse and potentially increase its valuation.
