Polished Wood Slab Appraisal

Polished Petrified Wood Slab on Custom Stand

This item is a decorative cross-section slab of petrified wood, professionally polished to a high-gloss finish on its primary face. The specimen features a deep charcoal to black internal coloration, indicative of a high carbon content or specific mineral replacement during the permineralization process. The outer perimeter retains the natural, rugged texture of the original tree bark, exhibiting a contrasting light tan or cream-colored sapwood transition zone. The slab is irregular in shape, following the organic contours of the ancient log, and is mounted on a minimalist black metal display stand consisting of two vertical prongs. This type of specimen typically dates back to the Triassic or Cenozoic eras, millions of years old. The craftsmanship is evidenced by the seamless mirror-like polish which reveals faint growth ring patterns under direct light. The condition appears excellent with no visible structural cracks, significant chips to the polished surface, or artificial coloring. The contrast between the dark, glassy interior and the rough, earthy exterior makes it a high-quality geological display piece.
