Faceted Crystal Ball Decanter Stopper

This item is a vintage-style decanter topper or stopper, likely crafted from high-lead crystal or exceptionally clear glass. The design features a large, spherical finial with multiple geometric triangular facets that catch the light, creating a sparkling refractive effect. The finial is mounted atop a tapered, multi-sided pedestal neck which transitions into a ground-glass shank. The shank is finished with a frosted matte appearance, which is a functional detail designed to create an airtight seal when paired with a matching decanter neck. In terms of dimensions, the piece appears to be approximately 5 to 6 inches in total length. The clarity of the material and the sharpness of the facets suggest high-quality craftsmanship, possibly in the style of well-known glassmakers like Waterford or Baccarat, though no specific acid-etched maker's mark is visible in the provided image. The condition appears to be very good with no obvious chips to the delicate facet edges or the bottom of the ground plug. The style is classic and formal, likely dating from the mid-20th century to the late vintage era. The prismatic fire seen within the facets indicates a high refractive index consistent with lead crystal.
