Murano Hand-Blown Art Glass Paperweight with Aventurine Inclusions

This is a substantial hand-blown art glass paperweight, characterized by its spherical form and vibrant aesthetic. The core features a brilliant ruby red encased within a thick layer of clear crystal glass. Scattered throughout the red interior are irregular inclusions of copperaventurine, which provide a shimmering, metallic sparkle reminiscent of goldstone. The base appears clear with subtle internal swirls, indicating a high level of craftsmanship in the layering technique. The overall construction is heavy and solid, typical of Italian Murano glass production from the mid-20th century, specifically the 1960s or 1970s. The surface shows a high-gloss finish with minimal visible scratches, suggesting well-preserved condition without major chips or fractures. No maker's marks or signatures are immediately visible from this angle, but the use of copper aventurine and the specific 'sommerso' style layering strongly point toward Venetian origin. The clarity of the crystal encasement and the richness of the red pigment serve as high-quality indicators for this collectible piece.
