AI Appraisal Estimate

This item appears to be a pressed glass bowl featuring a pale yellow or 'vaseline' glass hue with characteristic opalescent scalloped and ruffled edges. The interior is decorated with a complex geometric pattern consisting of cross-hatched, diamond-like motifs arranged in a radiating starburst configuration, interspersed with smooth, lobed panels. The piece exhibits a pearlescent or slightly iridescent finish common in Victorian-era style art glass. Small bubbles or inclusions may be present within the glass matrix, and the crimped rim shows a milky white opescence. While the user identifies this as a 'Davidson William & Mary ruffled bowl,' no maker's marks are visible in the photograph to provide a verified identification. The design is stylistically consistent with late 19th-century or early 20th-century British pressed glass, specifically the 'William and Mary' pattern attributed to George Davidson & Co. of Gateshead, though this remains an unverified hypothesis without physical inspection for registered design numbers or catalogs. The condition appears fair with no large chips or cracks visible from this angle, though minor surface scratches typical of aged glassware may exist.

Based on my visual review of the image, the bowl exhibits characteristics typical of Victorian-era pearline or vaseline glass. Per the user's submission, this is attributed to the George Davidson & Co. 'William and Mary' pattern (Registered Design No. 176566). Based on what I can see, the glass displays the classic primrose yellow hue with a milky white opalescent rim and a complex pressed geometric starburst pattern. However, I cannot verify the maker from a photograph alone; a physical inspection for a registered design number or specific mold markers would be necessary to support this hypothesis. This estimate assumes the piece is a period original from the late 19th or early 20th century in the fair condition described. The market for British pressed glass of this type remains stable among specialized collectors, though values are highly dependent on the intensity of the opalescence and the absence of 'flea bites' or internal bruising. If this item were found to be a modern reproduction or an unattributed piece 'in the style of' Davidson, the value would likely decrease to the $15–$25 range. To move toward a more certain identification, I would recommend an in-person examination by a glass specialist and a UV light test to confirm the presence of uranium, which is characteristic of genuine vaseline glass from that era. Because I am working from a photo, I cannot rule out the possibility of later 20th-century copies which frequently mimic these ruffled forms and color palettes.
