Ruby Red Cut-to-Clear Crystal Vase/Tumbler

This is a ruby red cut-to-clear crystal vase or perhaps a large shot glass/tumbler, showcasing a vibrant, deep red color that transitions to clear crystal through precise facets. The piece features intricate geometric patterns, including starbursts and diamond cuts that alternate with circular or oval motifs, particularly noticeable around the rim where the clear sections reveal the underlying red glass. The cutting is crisp and well-defined, indicating a high level of craftsmanship. The overall shape is cylindrical with a slightly flared rim and a thicker, stable base that also exhibits cutting. A small, dark, rectangular paper label is visible inside the rim, likely a manufacturer's sticker or a retail tag, though its details are illegible. The glass appears to be in excellent condition with no visible cracks, chips, or significant wear. The vibrant color and detailed cutting suggest it could be a piece of bohemian crystal or a similar European or Japanese (e.g., Kagami Crystal, Hoya) style glassware from the mid-20th century or later, known for its intricate cut-to-clear technique. The craftsmanship suggests a piece of good quality, designed for decorative appeal or serving fine beverages.
