Pair of large cognac glasses/amethyst crystal vases vintage Derenburg

Superb and rare pair of very large cognac glasses (which can also serve as vases or candle holders) made of striped/optical crystal in amethyst/intense violet color, manufactured by the German company Derenburg. Each piece still retains its original golden paper label from the period. Condition of the pieces: The first glass is in perfect condition, with no defects. The second glass has a very minor chip on the upper edge (clearly visible in the dedicated photo), which remains very discreet and does not affect the overall strength or beauty of the piece. Dimensions: Height: approx. 18 cm. Maximum circumference: approx. 42 cm. Ultra-secure packaging with reinforced protection for shipping.
