What it is

Regional/trade name for picture material

What to look for

Compare landscape-like bands and patches with Biggs and other picture materials. Pattern resemblance cannot distinguish a regional origin.

At the cutting bench

Orientation changes the apparent landscape. Cracks and matrix determine the usable face; no universal premium grade is inferred.

Under the loupe

Do not equate every Owyhee seller label with one mine or automatically place it in Idaho. Regional trade and precise provenance are different.

Source & collecting access

Current extraction and collecting permissions for a particular source are unknown.

Formation & evidence

The saved university reference documents Oregon-labelled Owyhee picture material and several trade variants. Deposit-specific formation has not been established for every label.

Collecting & trade context

Historical labels include Owyhee picture rock and jasper-agate wording. Preserve these as trade history rather than treating them as different mineral species.

Reading an old label

Preserve the exact name, dates, wrapping and associated pieces. Old-stock age alone does not authenticate a locality or imply exceptional value.

Color comparison limits

Brown/Tan, Yellow

What we know—and what we don’t

Visual resemblance can narrow a comparison. Material identity, locality attribution and documented provenance need separate evidence.

C&C Reference Collection

Authenticated reference photography is still being assembled.
