Modern decorative flint-knapped glass and stone knife

A decorative knife featuring a translucent, milky-white blade and a multi-toned stone handle. The blade is meticulously crafted using a technique stylistically consistent with modern pressure-flaking or flint-knapping, showing uniform scallop-shaped ripples across its surface. The material appears to be a variety of glass or translucent chalcedony. The handle is composed of polished stone with distinct segments: a dark grey section with linear white and black veining consistent with Picasso marble, and a pommel end of tan and brown stone exhibiting a fossilized or brecciated appearance. A thin metallic band, appearing brass-toned, serves as the bolster between the blade and handle. Near the pommel, there is a small, etched mark resembling a stylized 'JK' or a cross within a square, which may represent a maker's mark, though it remains unverified without physical inspection. The item appears to be in excellent condition with no visible chips or fractures on the delicate blade edges. This piece is consistent with 21st-century artisanal lapidary work rather than an ancient artifact, likely intended for display. The attribution is based on stylistic analysis of the flaking patterns and material combination, as no definitive labels are present.

Based on my visual analysis of the provided image, this item appears to be a contemporary decorative knife showcasing high-quality lapidary skill. I can observe meticulous flint-knapping on a translucent blade—likely glass or chalcedony—paired with a multi-stone handle. The handle exhibits characteristics consistent with materials such as Picasso marble. While I can see a mark resembling a stylized 'JK' near the pommel, I cannot verify this as a specific maker's mark without physical inspection and further research into modern knifemakers. This estimate assumes the piece is a high-quality artisanal work from the 21st century. The value of modern lapidary art is driven by the complexity of the flaking and the rarity of the stone materials used. Items of this type currently see moderate demand among collectors of modern primitive arts and desktop decor. Based on what I can see, the condition appears excellent, which is vital for the value of such a fragile blade; however, I cannot rule out microscopic fractures or structural instabilities through a photo. To confirm this estimate, an in-person examination is required to determine the specific mineral composition and to verify the origin of the maker's mark through provenance documentation. If the piece were found to be a mass-produced reproduction using lower-quality cast materials rather than hand-knapped stone, the market value would likely fall below $50. Conversely, if attributed to a highly recognized master of modern lithic art, the value could exceed the current range.
