The Material Integrity Index

The OAC score, for the whole category.

One number for luxury as a whole: how far, on average, the price of a luxury object sits above what public trade data says it cost to make. A nutrition label for the category, drawn together from every object the instrument has measured. The Hollowed Object, counted in aggregate.

How this is computed


By category

Where the distance is widest.

The same estimate, broken out by the kind of object. A category's average is a reading of the class, never a verdict on any single house within it.

How this is computed


Most spectacle

The widest gaps we have measured.

The named specimens where the distance between make-cost and price is greatest. Each is estimated from public trade records and shows its working on the Exposer.
