Great observation. I have sort of my own twist on the whole gem nameing thing. I only have four digits that consists of at least two letter and two numbers. There is also a hyphen. So an example of this would be Lavender Chalcedony 6D'9M.

The '6' is the Diamond he belongs to which is purple Diamond. Note that if a gem is rebellious, they will take that part of their identification name and replace it with a '0'. Some gems serve more than one diamond. So their identification name could be. 63D'9M.

The 'D' what planet they were born (formed) on. Each planet has an identification letter. So far, only 24 planets have active kindergartens. Meaning that the letters 'Y' and 'Z' have not been used.

The '9' is the gem placement. The number may be double or even triple if multiple gems of the same type have the same gem placement in the same body area.

The 'M' is the gem cut. If a cut is '0', then the gem cut is unique, rare, custom, or too complex.

Noble gems or high caste gems are not authorized to give their gem I.D. code.
