Source before spectacle

Four documented records, zero copied specimen photographs.

Authentic source media remain on their original sources because BOU006 has not independently established reuse permission. The abstract graphics below are record placeholders only.

Compare evidence fields

Comparison is source metadata only. It does not rank quality, rarity or value.

Choose two documented records to compare.

Cabinet boundary

What a specimen card does not prove.

A record preserves what a source actually states. Missing dimensions, treatment status or field identity stay missing rather than being inferred from an image or pattern.

Appearance

Not provenance

Color or pattern resemblance cannot assign an unknown stone to Yowah, Quilpie, Koroit or any other field.

Treatment

Not inferred

When a source does not state treatment or synthetic status, BOU records that absence rather than guessing.

Value

No appraisal

The cabinet does not turn visual characteristics into a price, rarity grade or investment judgment.

Specimen evidence model

Four separate boxes prevent one fact from pretending to be another.

Each documented specimen now carries a normalized evidence ledger in the active data revision.

01 · documented

Source record + provenance scope

What the cited record actually establishes, including locality only when explicitly stated.

02 · context

Field and formation context

Useful only after a documented relationship exists; never a shortcut for assigning origin.

03 · observation

Source-described or visible properties

Descriptive vocabulary stays separate from authenticity, treatment and value conclusions.

04 · unresolved

Unknowns + testing gate

Missing facts remain explicit, with expert gemological testing recommended when a consequential identity/treatment decision cannot be supported otherwise.
