AI Appraisal Estimate

A pair of heavy, semi-circular bookends appearing to be made of lead crystal or high-quality pressed glass. Each piece features a radiating fan silhouette with deep geometric cuttings. The pattern includes a central sunburst or shell-like motif at the base, from which vertical fluting extends outward, giving way to a cross-hatched or 'diamond' cut pattern near the scalloped perimeter. The items appear clear and colorless, displaying significant light refraction consistent with lead crystal glass. No maker's marks, etched signatures, or paper labels are visible in the provided image; consequently, a specific manufacturer cannot be attributed without in-person inspection for acid-etched marks common to makers like Waterford or Baccarat. The style is consistent with mid-to-late 20th-century decorative glassware. The pieces appear to be in good condition with no visible chips or cracks from this distance, though minor shelf wear on the flat bases would be expected. The heavy construction and sharp edges of the facets indicate a high level of craftsmanship.

Based on my visual examination of the provided image, these fan-shaped bookends appear to be high-quality lead crystal or pressed glass, likely dating from the mid-to-late 20th century. The intricate radiating fluting and diamond-cut patterns suggest a level of craftsmanship consistent with notable glass manufacturers; however, I cannot verify the presence of acid-etched signatures or hallmarks which are often found on the underside or edges of such pieces. Without an in-person inspection to look for these marks, I cannot attribute them to a specific maker like Waterford or Baccarat. My estimate assumes the items are in good condition; while no chips are visible, I would need to physically feel the edges and inspect the base for shelf wear to confirm. The current market for clear decorative crystal of this era is stable, though prices fluctuate significantly based on brand recognition. If these were confirmed to be from a premier studio through a verified mark, they would likely reach the higher end of the $80-$120 range. If they are unattributed pieces 'in the style of' major glassworks, the value would more likely reside in the $40-$60 range. To establish a more precise value, I would recommend a physical examination to search for subtle etchings and an assessment of the light refraction to determine the lead content of the glass. The presence of original labels or provenance documentation would also assist in refining this estimate. Without such confirmation, this value represents a fair market estimate for high-quality decorative glass of this style.
