Hampton Butte petrified wood

Silicified petrified wood; mineralized fossil material

Green to blue-green material with recognizable wood structure is a useful comparison candidate. The reviewed 9.4-inch seller slab supports green material; do not assume all Hampton wood is green.

What it is

Silicified petrified wood; mineralized fossil material

What to look for

Green to blue-green material with recognizable wood structure is a useful comparison candidate. The reviewed 9.4-inch seller slab supports green material; do not assume all Hampton wood is green.

At the cutting bench

Polished seller slab and WSU collection demonstrate cutting/display use. Wood replacement, fractures and hardness variation affect orientation and yield; specimen-specific assessment required.

Under the loupe

Compare other silicified wood and green jasper. Look for repeated cellular/grain organization rather than a single vein resembling grain. Even verified wood texture cannot establish Hampton provenance.

Source & collecting access

BLM documents Hampton Butte WSA, but that does not establish a collecting site or permissions. Current production, claim status and lawful extraction UNKNOWN.

The market notebook

Seller explicitly states this specimen has been sold. Realized price and sale date UNKNOWN. Seller-reported sold status; no independent transaction record.

Color comparison tags

Green, Blue, Brown/Tan, White/Cream/Clear

Geology & evidence limits

Specific specimen age unresolved: seller calls its slab Oligocene; a 2016 paper index describes a brown Hampton sample as Miocene. Neither age should be applied to every piece. Exact mineralization and green-color cause not independently verified.

Collecting & trade history

WSU Jacklin collection is institutional context for Hampton lapidary material. Estate labels can add provenance evidence, while appearance cannot authenticate the locality.

Reading old-stock material

Preserve original labels, receipts, packaging and associated pieces. Old-stock age does not authenticate a locality or justify a rarity premium.

How to read the color tags

Comparison tags, not origin evidence; non-dominant/secondary colors vary by specimen.

Still unresolved

Rights-cleared close-up of green wood and non-green examples; Resolve age at documented sample/site level; Identify color-bearing phases; Current legal access; Realized price

What we know—and what we don’t

Visual resemblance is a comparison clue, not proof of material identity, locality or documented provenance. Keep source labels and estate records separate from your visual assessment.

C&C Reference Collection

Reference photograph pending. Do not substitute an unlicensed dealer image or a similar-looking specimen of uncertain identity.
