Polished mineral tower or obelisk consistent with Epidote or Tourmaline

This item is an elongated, vertically oriented mineral specimen that has been carved and polished into a double-pointed, hexagonal-style obelisk or 'tower.' The specimen appears to be composed of a dark, greenish-black mineral with significant translucent to opaque inclusions that vary from olive green to yellowish-gold. The surface texture is uneven, showing a combination of high-gloss polished facets and recessed, rugged areas where the natural crystal habit remains visible. This ruggedness suggests the material is prone to splintering or has a fibrous structure, which is stylistically consistent with minerals like Epidote or Green Tourmaline, though positive identification is impossible without a physical hardness test or refractometer. The piece features a distinct termination point at each end. In terms of condition, there are visible surface fractures, pits, and internal inclusions characteristic of natural stone products. Some edges appear slightly abraded, likely occurring during the lapidary process or subsequent handling. No maker's marks, signatures, or branding are visible on the object; the identification is based solely on the visual appearance of the mineral luster, color, and common commercial lapidary shapes.

I have examined the provided image of a polished mineral tower, which is hypothesized to be composed of Epidote or potentially a Green Tourmaline specimen based on its dark olive to blackish-green coloration and fibrous-looking inclusions. Based on what I can see, the piece is a double-terminated lapidary object exhibiting high-gloss facets alongside natural, rugged recessed areas. While the visual evidence suggests a specific mineraloid structure, I cannot verify the exact mineral composition from a photo alone; physical testing such as a Mohs hardness test or refractive index measurement would be required to confirm the material. The value estimate of $45 to $85 reflects the current retail market for decorative mineral specimens of this size and polishing style. Condition plays a significant role in this valuation; the visible surface fractures, abrasions, and pitting noted on the facets are typical for natural materials but may slightly lower the appeal for high-end collectors. General market interest in 'crystal towers' remains steady, though prices vary significantly depending on the rarity of the stone. If this specimen were subsequently found to be a more common material, such as dyed quartz or a synthetic glass simulant, the value would likely fall below $15. To establish a more precise value and confirm the mineral's identity, an in-person examination by a gemologist or mineralogist is necessary. This report assumes the specimen is a natural stone product consistent with the hipothesized Epidote classification.
