zExclusive Petrified Wood Slice Black Heartwood Polished Face — Collector Grade Authenticated Fossil Specimen

zExclusive | Collector-Grade Petrified Wood Specimen

This authenticated petrified wood slice presents one of the most visually commanding contrasts found in fossilized wood: a deep black silicified heartwood core set against a warm tan bark rind boundary. The face has been precision machine-polished to a gallery-ready finish, revealing preserved wood grain structure and genuine permineralization color zonation — hallmarks of authentic silicified wood.

The reverse retains its natural rough bark rind, offering dual-sided display potential. Exhibit the polished face for dramatic visual impact, or present the raw reverse for educational and geological context. This duality is a meaningful value signal among serious collectors and natural history enthusiasts.

Authenticity is confirmed by visible wood grain patterning on the polished surface, natural bark-to-heartwood boundary transition, and the characteristic color zonation produced by true mineral replacement over geologic time. Condition is assessed as excellent — polished face intact, no major cracks, bark rind boundary cleanly preserved.

Specimen is estimated medium in size and carries a display-grade, mid-tier resale classification within the zExclusive authenticated fossil inventory. Weight: 1 lb. Exact dimensions are specimen-specific; please inquire for precise measurements prior to purchase.
