Mid-Century Modern Amethyst Sommerso Art Glass Bud Vase

A fine example of mid-century modern art glass, this bud vase features a slender, elongated form typical of the 1950s and 60s design aesthetic. It is constructed using the signature 'Sommerso' (submerged) technique, characterized by a deep amethyst or dark plum core encased in a thick layer of clear, colorless glass. The vase stands approximately 8 to 10 inches tall with a weighted, bulbous base that tapers into a long, slender neck, terminating in a subtly flared and trilobed rim. The base is expertly finished with a polished flat surface, showing a clear transition where the colored core meets the thick transparent exterior. Physically, the glass appears to be in excellent condition with no visible chips, cracks, or flea bites on the rim or body. The interior of the glass remains clear without signs of clouding or calcium buildup. While no maker's mark or signature is visible in the photograph, the style, high-quality execution, and teardrop color suspension are highly indicative of Murano craftsmanship (such as Seguso or Mandruzzato) or high-end Scandinavian production from the mid-20th century. The piece exhibits a consistent flow of color and heavy glass weight, signaling premium quality.

I have examined the digital representations of this Mid-Century Modern Amethyst Sommerso glass vase. This piece displays the hallmarks of Murano production, specifically the 'Sommerso' technique popularized by firms like Seguso Vetri d'Arte. The deep amethyst core is perfectly centered, showing excellent tension and control of the submerged layer. The trilobed rim is characteristic of 1960s Italian 'bolla' or tear-drop designs. Physically, the item appears in excellent vintage condition; the lack of 'sickness' (internal clouding) and the absence of chips on the delicate rim significantly bolster its marketability. The secondary market for unsigned Murano glass remains stable, though price appreciation is currently tiered. Pieces without a verified signature or original foil label are often attributed to the 'School of Murano.' Comparable sales for unsigned 8-10 inch Sommerso vases in this color palette typically range between $150 and $250. The value is driven by the height and the clarity of the clear encasement. However, there are limitations to this digital appraisal. Authentication without a signature is based purely on stylistic grounds. An in-person inspection is required to check for micro-scratches on the base (indicating age) and to verify the presence of 'pontil' marks or a professional factory polish. Scientific testing for lead content or refractive index could differentiate between Italian soda-lime glass and Scandinavian lead crystal, which would further refine the attribution. For high-level insurance purposes, physical verification of the base's wear pattern is essential to confirm this is a vintage mid-century specimen rather than a modern reproduction.
