Victorian-style mourning ring with black gemstone and seed pearls

This item appears to be an oval-shaped cocktail or mourning-style ring, stylistically consistent with mourning jewelry from the mid-to-late 19th century. The central element is a large, flat, polished oval gemstone that is oily black in appearance, consistent with onyx or glass. This is bezel-set within a yellow-toned metal frame, which is bordered by a halo of small, white spherical elements consistent in appearance with seed pearls. The metal possesses a dull golden luster, suggesting either low-karat gold or a gold-toned alloy. The outer edge of the setting features a delicate beaded or granulated texture. The ring is substantial in size, covering a significant portion of the wearer's proximal phalanx. No hallmarks or maker's marks are visible in the image to facilitate a more specific attribution. The craftsmanship shows intricate detail in the pearl setting, though there is visible surface wear and slight irregularities in the pearl alignment, which is common in older or handmade pieces. Because no marks are visible, its age and material composition remain unverified without physical testing.

Based on my visual examination of the provided image, this ring displays characteristics frequently associated with Victorian-era mourning jewelry, specifically the late 19th-century aesthetic. The central black stone, which appears consistent with onyx or glass, and the halo of seed pearls are typical of this period. However, I cannot verify the metal's purity or the organic nature of the pearls without physical testing, such as acid testing or magnification. The piece bears no visible hallmarks, meaning its attribution to a specific maker or geographic origin remains a hypothesis rather than a fact. My value estimate of $450 - $950 is based on the assumption that the mount is low-to-mid karat gold and the pearls are natural. This range reflects the robust collector demand for high-quality Victorian-style sentimental jewelry in the current secondary market. If physical inspection reveals the setting to be a base-metal alloy or plated, the value would likely drop to the $75 - $150 range as a costume piece. Conversely, if the metal is high-karat gold with high-luster natural pearls, the value could exceed the current estimate. To confirm these details, I would recommend an in-person assessment by a gemologist to perform a scratch test on the stone and verify the metal composition. Documentation of provenance or the discovery of a maker's mark under the bezel would further clarify its market position. Without such evidence, the item must be treated as being 'in the style of' the Victorian period rather than a documented antique.
