Polished Flint Nodule Black Cream Gray Banded — Lapidary Specimen Collector Grade 0.88 kg

This polished flint nodule displays bold color contrast between a jet-black cortex and a chalcedonic interior banded in cream, warm gray, and smoky white. Golden-ochre iron oxide inclusions add depth and character to the surface, making each view slightly different depending on the angle of light.

The high-gloss polish brings out clean conchoidal fracture patterns that are characteristic of quality flint — the kind of detail lapidary workers look for when evaluating chert and flint material. Banding is well-defined and consistent, running across the exposed face in distinct zones.

Flint is a microcrystalline variety of silica (amorphous), formed through the replacement of calcium carbonate in sedimentary rock. The waxy luster and tight grain structure are hallmarks of genuine flint, distinguishing it from coarser cherts. This nodule reads as mid-grade collector material: presentable enough for display, structured enough for lapidary study.

Listed as a single specimen. Weight: 0.08 lbs. Quantity available: 1. No two nodules are alike — what you see is what you ship.
