How could photogrammetry be applied to gemology? I can see the spacial application could be somewhat relevant in geology and geography, but not in mineralogical or gemological application.
Please enlighten me if I've misinterpreted the application.

I would use it for many things like making micro measurements on crystals, or study the geometry of cut stones. I'm sure I could find many other fun ways to use such software

Couldn't one physically take all the measurements and determine angles on a xl or cut gem, using a Presidium gauge, a table gauge with magnification and a goniometer?
Gemologists usually work with the stone in hand, not a photo.

True, still if one would want to calculate angles or take other measurements of microscopic inclusions this would be way to do it. Some of these software can also analyze image patterns and recognize/count particles. With stereo images you can also do it in 3D
I know that Diamond Cutting software exist that are used to maximize the yield of each stone. Using multiple images it will build a 3D model and compute. This is a form of photogrammetry
