Rare Vintage Karel Malvanek for retailer Beranek Glassworks Vase Encased Pink with Purple Swirl

This amazing unique vase is signed by the artist Karel Malvanek for Beranek Glassworks in the 1990's. The vase is pink with a purple swirl encased in clear glass. The vase has some scratches on the sides and one on the rim (see photos). There is also scratching on the bottom. The piece is being sold "as is". The vase is almost 8lbs and stands 12.2 inches and 3.1 inches in diameter. There is an optical allusion of the size of the flower hole, it is only 1 inch in diameter retailer but looks larger through the glass. A very rare piece and unable to find another like it.
