When a maker’s reputation is involved, and they’re close to the artefact, quality becomes a personal issue. A maker does not want their name attached to a poor quality artefact.
This often means that well-crafted artefacts are better quality. This might be a relatable practical quality, but it could also be a luxurious quality.
Well-crafted artefacts are often expensive, if they’re for sale. This is owed to the skill, quality, and rarity mentioned earlier. People recognise that the artefact is worth more money.
Note that this quality can be regardless of the materials used. Even if cheap or poor materials are used, an artefact can still be high quality due to the quality of the craft involved.
