AI Appraisal Estimate

A decorative glass object featuring a teardrop or flame-like silhouette, appears to be constructed of solid, clear colorless glass. Centrally suspended within the glass is a controlled internal spiral element, displaying bands of reddish-burgundy and pale yellow-green. The object rises to a rounded point at the top and appears to sit on a flattened base, though the base itself is not fully visible. The surface appears smooth with high lucidity, exhibiting multiple reflections from surrounding objects. While the user identifies this as 'Signed PM', no signature is legible in the provided photograph, and the attribution is currently unverified. The form and internal ribbon decoration are stylistically consistent with late 20th-century art glass, appearing similar in manner to studio glass works produced by companies such as Perthshire Paperweights (whose 'PM' monogram denotes the maker Peter McDougall), though this cannot be confirmed without a physical inspection of the mark. Overall condition appears good with no visible chips or fractures, though fine surface scratches consistent with shelf wear may be present on the base.

I have evaluated the provided image of a teardrop-shaped glass paperweight featuring a reddish-burgundy and pale yellow-green internal spiral. Per user submission, the item is identified as 'Signed PM,' which I have treated as a hypothesis for this estimate. Based on the visual evidence, the form and internal ribbon decoration are stylistically consistent with late 20th-century studio glass, specifically works associated with Perthshire Paperweights and the monogram of Peter McDougall. However, I cannot verify the signature from the photograph, and a physical inspection is required to confirm if the mark is consistent with known examples from this maker. The estimated value reflects typical market demand for signed studio glass of this specific quality and region of origin. If the attribution to Peter McDougall is correct, the item would likely command a price in the $100–$250 range. Based on what I can see, the piece appears to be in good condition, though value would be negatively impacted by any undetected base wear or internal bruising. I cannot confirm authenticity through a digital image alone; to do so would require an in-person examination to verify the 'PM' mark and glass density. If the item lacks a signature or is determined to be a later production 'in the style of' rather than by the specific maker indicated by the owner, the value would likely decrease to a range of $30–$60 as a decorative glass object. Similar works of this type currently see stable interest among collectors of Scottish art glass, though prices remain sensitive to the presence of a verifiable maker's mark.
