AI Appraisal Estimate

This is a fine ceramic dinner plate from the 'Manosque' collection, produced for Williams Sonoma and manufactured in Portugal. The piece is constructed from high-fired stoneware or earthenware, featuring a lustrous, creamy white glaze that covers the entire surface. Its most distinguishing physical characteristic is the elegant scalloped or lobed rim, which incorporates subtle architectural ribbing or 'ear' details at opposing sides, reminiscent of traditional French country or Provincial styling. The plate exhibits a clean, smooth well with a gentle transition to the decorative border. Measuring approximately 10 to 11 inches in diameter, the craftsmanship indicates a high-quality commercial production consistent with Portuguese ceramic traditions known for durability and classic aesthetics. Under close inspection, the glaze appears uniform with no immediate evidence of crazing, chips, or significant utensil marks, suggesting it has been well-maintained. The style is contemporary yet inspired by 18th-century European silhouettes, making it a versatile piece for formal or casual dining. Although the maker’s mark is not visible in the top-down view, it would typically feature the 'Williams Sonoma', 'Manosque', and 'Made in Portugal' stamps on the reverse. The condition is excellent, showing a vibrant reflective sheen and no visible structural repairs.

Based on my visual examination of the Williams Sonoma 'Manosque' dinner plate, I find it to be a faithful representative of high-quality Portuguese stoneware. The creamy white glaze exhibits a consistent vitreous luster, and the scalloped rim with its characteristic 'point' details remains crisp, suggesting the mold-cast quality is intact. The condition appears to be 'Excellent' with no visible crazing, chips, or surface dulling typically associated with heavy dishwasher use or metal utensil abrasion. Market analysis indicates that the Manosque pattern is a popular, albeit discontinued, line for Williams Sonoma. The secondary market remains stable because collectors frequently seek replacements for broken pieces in their larger sets. Current comparable sales on platforms like eBay and Replacements, Ltd. show individual dinner plates consistently fetching between $25 and $40 depending on the exact diameter and state of wear. While not considered 'rare,' there is a persistent demand for authentic Portuguese-made dinnerware due to its durability compared to cheaper alternatives. Key value factors include the 'Made in Portugal' origin and the lack of surface staining. However, physical limitations of this digital appraisal exist: I cannot verify the underside maker's mark to confirm absolute authenticity or identify minor tactile imperfections (pinholes or 'flea bites') that might downgrade the grade from 'Excellent' to 'Good.' A full authentication would require an in-person inspection of the backstamp, a weight/density check to differentiate stoneware from lighter earthenware, and a tactile 'ring test' to check for internal structural cracks not visible to the naked eye.
