Carved organic material pendant in the shape of a mermaid with decorative metal mounts

This pendant features a central element composed of carved organic material, stylistically consistent with bone, tusk, or ivory, shaped into the form of a mermaid. The material displays a yellowish, aged patina with visible graining and surface hairline cracks, consistent with an older piece of organic origin. The carving represents a feminine figure transitioning into a curved tail. The piece is mounted with ornate metalwork at the head and the base of the tail, including a silver-toned metal bale for suspension. A green, rectangular-cut stone is set into the top mount, while a dark red, faceted stone is set into the lower mount. The owner identifies these as a 4mm x 4mm emerald and garnet, respectively, and notes the metal is silver; however, without metallurgical testing or gemological analysis, these remain unverified claims. The craftsmanship exhibits detailed filigree and granulation in the metalwork. The item lacks visible hallmarks or maker's marks in the provided image. The overall aesthetic is consistent with a bohemian or eclectic maritime-themed design, possibly influenced by Victorian or revivalist jewelry styles, though its true age and origin are unverified without physical inspection.

Based on my visual analysis of the provided image, I have examined this 4-inch pendant featuring a carved organic element in the form of a mermaid. Per user submission, the piece is identified as carved tusk with a 4mm x 4mm emerald and garnet set in silver. While the material displays a yellowish patina and graining consistent with aged bone or ivory, I cannot determine the exact biological origin or the metal purity from a photograph alone. The presence of surface hairline cracks suggests age, but whether this piece dates back hundreds of years would require specialized forensic testing. The value estimate is predicated on the hypothesis that the stones and metal are as described by the owner. If the emerald and garnet are natural and the metal is high-grade silver, the intricate filigree and maritime subject matter appeal to collectors of Victorian-revival or eclectic jewelry. However, without visible hallmarks, any attribution to a specific era or maker remains a working assumption. Items of this type often see moderate demand in the secondary market as curiosity pieces. I must note that if the piece is found to be a modern composite or synthetic material rather than tusk, or if the stones are glass or lab-grown, the value would likely decrease to the $100-$200 range. To establish a more precise value, a physical inspection by a gemologist to verify the stones, a metallurgical test for silver content, and a consultation with an expert in organic materials are necessary. Authenticity cannot be established without provenance documentation or scientific verification.
