Natural ageing and artificial ageing: look for relationships, not colour alone

When you see dark or green areas, white powder, soil, oil sheen or wear, do not first label it ‘old’. Ask instead: what is the material, where is it located, and does it share a history with the mold, structure, breaks and other marks? A long-circulated amulet may have been worn, cased, cleaned, repaired or stored again; a cache piece is affected by soil, moisture and salts. Natural ageing has no single fixed appearance that fits every amulet.

Start with material: metal and powder need different measures

On metal pieces, surface change comes from alloy, casting, sweat, air, soil and storage. Stable oxide layers, wear and local corrosion may coexist; loose, powdering or spreading corrosion is not automatically ‘good age’ and may be an active condition needing conservation. Powder, clay and herbal pieces call for attention to particles, binding, shrinkage, layers, chips and pressure points. Their colour can be altered by oil, dust, casing and cleaning, so darkness alone is not natural age.

The key to natural traces is whether the marks explain one another

A stronger observation is not a search for a magical ‘old look’, but for relationships: are raised areas more worn, do recesses hold plausible accumulation, do breaks, cracks and surface layers remain coherent, and do covered versus exposed areas differ in understandable ways? These are questions, not single-item verdicts. What matters is that several details point to one history of the object, rather than every line being made uniformly and theatrically old.

Artificial ageing often fails because its story does not hold together

Added colour layers, oil, soil or chemical treatment can be persuasive in a photograph; their problems often appear only under magnification, raking light or a changed angle. Colour may sit only on the surface while crossing areas that should differ; highs and lows may look equally fresh; layers inside and outside a crack may not connect; or a claimed long-worn piece may lack plausible contact wear. None automatically proves artificial ageing, but each is a reason to pause, compare known specimens, or seek someone experienced with the same material.

Photographs can screen; they cannot replace inspection

1. 01Ask for clear original images of front, back, sides, thickness and key details; view the same areas in both neutral and raking light when possible.
2. 02Ask first about oiling, cleaning, repair, recasing or soaking. These are not automatically wrong, but they change how the surface should be read.
3. 03Compare images with reliable specimens of the same edition and material; do not force a standard from a different period or material.
4. 04For a substantial purchase, inspect the object, record its present condition, and agree on review and return terms. If scientific testing is used, read its result alongside comparable specimens and the full context.
