Jasper Rough Appraisal

Raw Jasper Specimen

This item is a raw, unpolished mineral specimen, primarily identified as a form of Jasper, possibly a variety of Owyhee or Picture Jasper based on its distinct color palette and sedimentary appearance. Physically, the specimen measures approximately 3 to 4 inches across and displays a rugged, irregular morphology. Its color profile is dominated by earthy mustard yellows, ochre, and deep siennas, with subtle hints of reddish-brown and muted grey-blue visible in the banded or dendritic-like patterns. The surface texture is notably coarse and matte, exhibiting a granular consistency typical of microcrystalline quartz with high impurity content. Notable features include intricate, swirling patterns or 'scenes' created by mineral deposition, which are characteristic of sedimentary formations. The condition appears to be entirely natural and unworked, with no signs of mechanical polishing or lapidary intervention. There are visible crevices, pits, and small surface fractures which are inherent to the natural growth and extraction process rather than post-extraction damage. No maker's marks or signatures are present as this is a natural geological product. Its age is geological, likely dating back millions of years. This specimen is valued for its unique natural aesthetic, with the 'landscaped' appearance of the mineral bands serving as a primary quality indicator for collectors of rough mineral specimens.
