CM here! ✋ Today, I was curious about how the sapphire sorting process works in our office. I keep seeing hundreds and hundreds of emerald lots in front of my eyes every day, but I have no idea how they are sorted. So I asked some of our gemologists in our office, and one of them told me how he manages the entire process:
The first phase is preliminary sorting. He identifies each stone and sorts them between dark and light colors.
Then, from each produced category, he sorts them into low, medium, and dark quality.
