Jewellery Quality Control: What a QC Inspector Actually Checks
4 September 2026 · JewelTasks Team
QC is the last gate before a piece reaches a customer, and the cheapest place to catch a problem.
Weight and purity
Against the job card, every time.
Setting
Every stone checked for tightness. This is where returns come from.
Finish
Polish quality, no file marks, no solder showing.
Hallmark
Correct marks present and legible.
The mindset
A good QC inspector is unpopular for a week and valuable for years.
