Dear Mr. Dubois,
Here are the answers to your questions
What is your current rate of falling stones?
We do not have the actual figures. But, our buyer has claimed about
3 - 4 out of approx 7,500 that we have sent him.
What QA/QC procedures does your factory applied?
Ultrasound and hand testing with a pin. All departments have
experienced supervisors who watch over the operations.
How many stone setter do you employ? are they all "in house"
setters or you sub contract the job as well
About 10 setters. When the orders are more, we bring in setters to
do the extra work.

our message bounced back.
