AI Appraisal Estimate

This is a circular glass bowl produced by Arcoroc France, featuring the 'Diamant' pattern, which is characterized by its intricate pressed diamond and starburst motifs. The piece is constructed from heavy, clear tempered soda-lime glass, a material Arcoroc pioneered for mass-market durability. The design features a central 12-point starburst embossed on the interior floor, surrounded by a band of relief-molded diamond points (hobnails) that transition into 12 larger vertical rays or wedges extending up the side walls. Notable markings include the embossed 'ARCOROC' and 'FRANCE' text in a circular format surrounding the central starburst. In terms of condition, the glass retains good clarity, though some minor surface abrasions and light scratching are visible, consistent with household use. There are no significant chips or cracks apparent in the photograph. This style represents mid-to-late 20th-century mass-produced glassware, likely dating from the 1970s or 1980s. The quality is indicative of high-volume industrial molding, designed for both aesthetic appeal and utilitarian strength. The scalloped edges and light-refracting geometry are hallmarks of the Arcoroc Diamant line, making it a popular choice for both domestic and commercial food service during its production peak.

Based on a visual examination of the provided image and description, this is an Arcoroc France glass dessert bowl in the 'Diamant' clear pattern. Authentic examples of this glassware are common, as Arcoroc mass-produced these tempered glass pieces for decades, particularly peaking in the 1970s and 1980s. The presence of the embossed 'ARCOROC FRANCE' mark on the interior is consistent with authentic production. The condition appears to be fair to good; while there are no obvious chips or cracks visible, the reported minor surface abrasions and light scratching are typical for utilitarian pieces of this age and slightly detract from the value. Market conditions for mass-produced mid-to-late 20th-century clear glassware are generally soft. While the heavy, durable nature of Arcoroc makes it a practical collectible, the 'Diamant' pattern is very common and lacks the rarity or high demand of designer or art glass from the same era. Comparables on secondary markets (online auctions, antique malls, thrift stores) typically sell for very modest amounts, often bundled in sets. A single bowl of this type rarely commands more than a few dollars. Significant factors impacting value include the lack of rarity and the piece's utilitarian, mass-market original purpose. Please note that this appraisal is based solely on photographic evidence and description. While authenticity is highly likely given the item's low reproduction risk, physical examination would confirm the exact wear and glass quality.
