AI Appraisal Estimate

A set of four circular glass dinner plates featuring a distinctive teal or deep turquoise translucency. The design follows a contemporary organic aesthetic, likely from the Corelle Hearthstone 'Simplicity' or 'Lake' collection, dating from the late 20th to early 21st century. The plates are constructed from heavy pressed glass with a smooth, glossy top eating surface and a highly textured underside. This texture consists of dense, radial ribbing or 'rippled' lines that catch and refract light, emanating from the center toward a gently scalloped or irregular 'hand-finished' style rim. These undulations on the edge provide a rustic, artisan appearance that contrasts with the uniformity of the pressed pattern. The glass is thick and durable, exhibiting quality craftsmanship typical of modern consumer glassware meant for daily use. Condition-wise, the plates appear to be in good utilitarian state, though they are currently bound together with clear adhesive packing tape, which may leave residues or conceal small rim chips. No major cracks or deep scratches are visible in the provided view, but light surface wear consistent with stacking is to be expected. There are no immediate visible maker’s marks in the crop, but these typically feature backstamps on the bottom center.

Based on my examination of the four Teal Rippled Corelle Hearthstone dinner plates, I have assessed them as genuine examples of Corelle’s early 21st-century stoneware/glassware line. The 'Simplicity' or 'Lake' aesthetic is highly recognizable due to the radial ribbing and vibrant teal translucency. Upon visual inspection, the structural integrity appears sound; however, the presence of adhesive packing tape is a point of concern. While used for bundling, tape can hide 'flea bites' on the rims or leave chemical residues that require professional cleaning to avoid marring the glossy surface. The market for Corelle Hearthstone remains steady among collectors of 'modern vintage' kitchenware, as these pieces are prized for their durability and stackability. Recent comparable sales for sets of four dinner plates in this specific rippled pattern typically range from $35 to $65 depending on the regional market and buyer demand for the specific colorway. Teal remains a desirable mid-range color, though it is not as rare as some limited-edition matte glazes. Limitations of this appraisal include the inability to inspect the plates individually for surface scratches (utensil marks) or to verify the backstamp under the tape. A full authentication would require removing the adhesive to check for the 'Corelle Hearthstone' mark on the base and a tactile inspection for micro-cracks or heat-stress fractures. No scientific testing is required for this class of consumer glassware, but provenance regarding original purchase or usage history would assist in confirming the exact production window.
