AI Appraisal Estimate

This is a large circular stoneware plate featuring a design from the Lisboa collection by Costa Nova, a renowned Portuguese manufacturer. The aesthetic is inspired by traditional 18th and 19th-century Portuguese tiles (azulejos), showcasing complex blue and white floral and scrollwork motifs in a collage-style arrangement. The plate is finished with a high-gloss glaze that exhibits significant 'crazing'—a network of fine hairline cracks across the surface that is characteristic of this specific artisan series, intended to give an antique appearance. The coloration involves varied shades of cobalt and indigo blue against a creamy off-white background. Upon close inspection, small red-brown speckles or 'freckles' are visible, which are a intentional part of the reactive glaze process. The edge features a subtle dotted or beaded border detail in blue. While the crazing is intentional, it can lead to staining over time if used for acidic foods. This contemporary piece, likely manufactured within the last 10-15 years, replicates the rustic, hand-stamped quality of antique ceramics while utilizing modern, high-fired stoneware for enhanced durability in microwave and dishwasher use.

I have conducted a visual examination of the Costa Nova Lisboa Collection Stoneware Charger Plate. Based on the provided imagery, the piece appears to be an authentic example of contemporary Portuguese stoneware, characterized by its signature 'azulejo' tile-inspired motif and intentional crazed glaze. The condition is assessed as excellent, with the visible surface cracking and iron speckling noted as intentional aesthetic features of the reactive firing process rather than post-production damage. In the current secondary market, Costa Nova is highly regarded for its 'new-antique' aesthetic, though as a mass-produced contemporary line, it does not possess the rarity of the 18th-century ceramics it emulates. Comparables for individual charger plates from this collection typically realize between $30 and $55 in online auctions and upscale consignment venues. The most significant factor impacting value is the utility of the piece; while decorative, its microwave and dishwasher safety maintains its appeal for daily use. However, collectors should note that the intentional crazing can absorb oils over time, which may lead to discoloration. Without a physical inspection, I cannot verify the integrity of the foot ring or detect micro-chips along the beaded edge. Full authentication would require confirming the stamped manufacturer’s mark on the reverse and checking for third-party seconds quality marks. This appraisal assumes the item is a first-quality production piece without hidden structural flaws.
