Precision Cut vs Commercial Cut Gems

I do faceting demonstrations for our club and like to put props together to show the difference between commercial faceted stones and fine faceted stones (using “fine faceted” loosely here.) 


I bought a parcel of garnets recently for some of the larger stones. This is a comparison between two stones in the parcel. The one on the right is typical in the parcel, the one on the left is after re-cutting. Both are about 5mm.
