Vintage Intaglio Etched Crystal Cabochon

This item is a small, heart-shaped or teardrop-shaped clear glass or crystal piece, measuring approximately 0.5 to 0.75 inches in diameter. The primary feature is a sophisticated frosted intaglio etching of a floral motif, specifically a five-petaled flower with central stamen detailing surrounded by three leaves. The etching is executed on the reverse side of the translucent material, creating a three-dimensional effect when viewed from the smooth front surface. The material appears to be a high-quality lead crystal or optical glass, indicated by its clarity and light-refracting properties against the blue background. The edges appear somewhat irregular or possibly hand-finished, suggesting it may have been an inset for jewelry such as a brooch or a locket. There are no visible maker's marks or signatures in the photograph, though the style is reminiscent of mid-20th-century decorative glass techniques used by European manufacturers. The condition shows minor surface scratches and some dust accumulation, but no major chips or structural cracks are evident. The craftsmanship is refined, with the frosted depth of the intaglio providing a soft, luminous quality to the botanical design.
