Overview
This is a heavy, geometrically faceted art glass scent bottle or petite decanter crafted in dichroic/cased crystal. The glass displays vibrant color-shifting properties characteristic of neodymium (Alexandrite) or sommerso glass, shifting between sapphire blue, amethyst, and teal under varied lighting.
Story
Cold War Czech glassmakers secretly revolutionized optical chemistry in the 1960s. Rare-earth elements like neodymium were fused into crystal, creating pieces that magically shift color as you walk between daylight and incandescent lamps.
Maker / Origin
Czech glasshouses such as Moser and Borské Sklo led the world in sculptural, heavy-cut art crystal during the postwar era. Designers like Josef Hospodka, Pavel Hlava, and Oldřich Lípa transformed traditional Bohemian gem-cutting techniques into bold, architectural modernism that bypassed Soviet Socialist Realism restrictions.
Condition & Value
Appears in very good condition with crisp, sharp facet edges and no visible structural cracks. The ground base and stopper peg appear intact. Pristine condition on high-facet crystal is essential, as edge chips can reduce value by 20–40%.
