Cut-glass-style highball drinking glasses

A pair of transparent drinking glasses, identified by the owner as 'drinking glasses' (unverified). The items appear to be highball or water glasses featuring a decorative cut-glass design. The pattern consists of vertical fluting or ribbing on the upper portion of the vessel, transitioning into a diamond-cut or cross-hatched textured pattern near the weighted base. The glasses appear to be made of heavy glass or lead crystal, though material composition cannot be confirmed without physical testing for mineral content or weight. Stylistically, the faceted geometric pattern is consistent with mid-to-late 20th-century glassware design, frequently seen in patterns by manufacturers like Marquis by Waterford or Mikasa, though no maker's marks, signatures, or acid-etched logos are visible in the provided image to confirm a specific brand. Both pieces appear to be in good used condition with no visible chips, cracks, or clouding from hard water deposits. The identification is hedged due to the absence of visible branding or packaging to establish a specific manufacturer or manufacturing date.

Based on the provided image, I have examined this pair of highball drinking glasses. The items feature a classic cut-glass aesthetic with vertical fluting and a diamond-textured base. While the weight and ring of the material cannot be verified from a photograph, they appear consistent with heavy glass or lead crystal. Per the user submission, these are identified as 'drinking glasses,' and my analysis treats the attribution to mid-to-late 20th-century manufacturers like Marquis by Waterford or Mikasa as a hypothesis only. I cannot verify the presence of acid-etched logos or signatures through the image, and therefore no specific brand provenance can be established. These glasses appear to be in good used condition. My value estimate of $40 to $80 assumes the pair represents high-quality crystal from a recognized mid-market manufacturer. This estimate takes into account the steady demand for classic barware in the secondary market. However, without a confirmed hallmark or signature, these must be treated as 'in the style of' such makers. If a physical inspection were to confirm a prestigious maker's mark, the value might sit at the higher end of the range. Conversely, if they are found to be modern soda-lime glass reproductions with pressed rather than cut patterns, the value would likely drop to $10 to $20 for the pair. To provide a more accurate valuation, a physical examination is required to verify the lead content, weight, and any micro-etched branding on the base. Provenance documentation or the original packaging would also be necessary to transition this from a hypothesized attribution to a more certain identification.
