AI Appraisal Estimate

This is a commemorative heavy-weight lead crystal beer mug or tankard produced by Edinburgh Crystal. The item features a prominent sandblasted or acid-etched logo celebrating 'ARAMCO FIFTY YEARS OF ACHIEVEMENT' (1933-1983), including the numeral '50' and Arabic script within a rectangular border. The lower half of the mug is decorated with a classic deep diamond-cut and wedge-cut pattern, characteristic of the 'Star of Edinburgh' or similar traditional Scottish high-quality crystal styles. It consists of clear, high-brilliance glass with an applied thick C-shaped handle. The craftsmanship is evident in the sharp, crisp edges of the hand-cut facets that provide excellent light refraction. Given the Aramco milestone, this piece dates to approximately 1983. The condition appears excellent with good clarity and no visible chips, cracks, or heavy scratching in the photograph. The base is likely thick and polished, typical of fine lead crystal barware which provides substantial heft and stability. These items were often given as corporate gifts to long-term employees or executives during major company anniversaries.

Based on my visual examination of this Edinburgh Crystal tankard, I find it to be a high-quality example of lead crystal commemorates commissioned for the Aramco 50th Anniversary (1933-1983). The item displays the characteristic brilliance and sharp hand-cut facets associated with the 'Star of Edinburgh' pattern. The etching is crisp, indicating a professional execution consistent with corporate gifting standards of the early 1980s. The condition appears excellent, with no visible clouding or flea bites, which often plague lead crystal of this age. Physically, these pieces are desirable for their significant heft and refractive index. From a market perspective, value is driven by two segments: collectors of luxury Scottish crystal and enthusiasts of oil industry history or Aramco memorabilia. Similar Edinburgh Crystal corporate commissions typically realize $100-$150, but the 'Aramco 50 Years' branding adds a specific niche value that can push results toward the $250 mark in a specialized auction. Limitations: This appraisal is based on photographic evidence. I cannot verify the presence of the 'Edinburgh Crystal' acid-etched mark usually found on the base, nor can I check for microscopic interior scratches or structural stress fractures without a physical loupe inspection. For definitive authentication, I would require an in-person assessment of the weight (to confirm lead content) and original presentation packaging or provenance documentation linking the item to a former employee of the period.
