AI Appraisal Estimate

This is a fine example of an American Brilliant Period cut glass nappy or small serving bowl, likely dating from the 1880s to 1910s. The piece is crafted from thick, high-lead content crystal, which provides its exceptional clarity and characteristic brilliance. The design features a complex 'Hobstar' and 'Fan' motif, with a large central six-pointed star multifaceted and surrounded by intricate cross-cut diamond and checkered patterns. The scalloped rim is finished with deep vertical serrations, often referred to as a sawtooth edge. The craftsmanship is evident in the sharpness of the hand-cut facets and the depth of the miter cuts, which catch and refract light across the entire surface. In terms of condition, the glass appears bright with no significant clouding or 'sickness.' There are minor, expected signs of age including surface scratches to the interior of the well and some micro-nibbles or minute flea bites along the sharpest peaks of the sawtooth rim, which are common for authentic pieces of this era. No major chips, cracks, or professional restorations are immediately visible. While no specific maker's mark is discernible in the image (as many were only acid-etched and wore off), the complexity and quality of the pattern align with major manufacturers of the period such as Libbey, Hoare, or Hawkes.

Based on my visual examination of the provided imagery, this American Brilliant Period (ABP) nappy exhibits the high lead content and intricate hand-cutting characteristic of the 'Brilliant' era (1876–1917). The 'Hobstar', 'Fan', and cross-cut diamond motifs are executed with deep miter cuts that indicate high-quality craftsmanship, likely from a reputable house such as Libbey or Hawkes. The clarity of the blank is excellent, showing no signs of 'caking' or glass sickness. The presence of 'flea bites' on the sawtooth rim and light interior scratches is consistent with authentic usage and actually supports its antiquity. Currently, the market for ABP glass is specialized; while common shapes like nappies are abundant, those with high-relief cutting and superior clarity maintain steady demand among collectors. The value is tempered by the absence of a visible acid-etched signature and the minor rim damage noted. Please note that this appraisal is based solely on digital images. A definitive authentication would require a physical inspection to verify the 'ring' (resonance) of the lead crystal, weight, and the presence of specific tool marks. I would also recommend a UV light test to check to see if the glass fluoresces properly for the period. Provenance regarding the original purchase or previous collection history would further solidify its valuation.
