Opal and Gold Tone Organic Medallion Pendant

This is an exquisite vintage or antique opal pendant, crafted in an organic, free-form design. The central element is a large, polished, tear-drop or pear-shaped white opal cabochon, set elegantly within a gold-toned metal frame. The opal exhibits a captivating play of color, with subtle flashes of red, orange, and green spectrums visible across its luminous, pale white surface. The backplate for the setting is a highly ornate, openwork design, appearing like a network of irregular cells or possibly coral, which contributes to its unique aesthetic. The frame's texture is uneven, suggesting an organic motif or a handcrafted finish. The metal is a warm, possibly rose or yellow gold, showing some natural patina commensurate with age, particularly in the recesses of the openwork. There are no obvious signs of major damage or repairs, and the stone appears to be securely held by several prongs. A small bail, designed for attachment to a chain, is visible at the top. The overall craftsmanship suggests a well-made piece, likely from the Mid-20th Century or earlier, given the style and material characteristics. The design is somewhat Art Nouveau or Art Deco-inspired, blending natural forms with geometric undertones, showcasing good quality and attention to detail. This pendant would likely be a statement piece when worn.
