Edinburgh Crystal Aramco 50th Anniversary Beer Mug

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.
