Beautiful vintage Rubina art glass decanter with cranberry-to-clear color gradient, ruffled rim, and thumbprint body. Hand-decorated with enamel floral motifs in white, yellow, pink, green, and brown. Original clear glass stopper included. The base is hand-engraved with the number “10”, likely a factory inventory or matching mark from production. This type of mark was commonly used in the late 19th-early 20th century to match stoppers and decanters or to identify molds. Such marks are valued by collectors as a sign of original, hand-finished production rather than modern reproduction. The clear glass stopper appears original to the piece, fitting snugly and matching the style and age, though no visible number is present on the stopper. Condition: Very good original as-found condition. No chips, cracks, breaks, or repairs.
