Vintage cobalt blue crystal vase

This appears to be a vintage cobalt blue cut-to-clear crystal trumpet vase, likely of Bohemian or Czech origin. This style features two layers of glass, an inner clear layer and an outer colored layer, which are then hand-cut to create contrasting facets and patterns. Key Characteristics Material: It is made of hand-cut, full-lead (24% PbO) crystal, a material known for its weight, clarity, and the ability to produce a bell-like ringing sound when tapped gently. Color & Design: The vibrant cobalt blue overlay is cut away in large oval or "thumbprint" panels and spear-like patterns, revealing the clear crystal underneath. Origin & Era: This style is characteristic of traditional Bohemian glassmaking, with similar examples often dating from the mid-20th century (circa 1960s). Maker: The piece is likely unmarked, a common occurrence for these items, though similar patterns have been associated with manufacturers like Nachtmann, Moser, or various Polish factories.
