Quality

The quality item property is a descriptive property added in patch 1.69. It indicates how well an item was made but has no intrinsic use; rather, it was provided for custom content to make use of (without requiring a hak pak to define new item properties). No standard items were given this property.

There are several types (technically cost parameters) of this property, namely unknown, destroyed, ruined, very poor, poor, below average, average, above average, good, very good, excellent, masterwork, godlike, raw, cut, and polished.
