The following photo was taken directly from my Digital Microscope.
This photo is of a "Milgrain" tool. It shows the rotating wheel that creates the mini-dots along a raised metal edge.
Here is an enlarged view from this microscope that was taken at 600x power magnification.
The next step is to curve the back end of the claw and then flatten the top of the claw.
I examined these claws and thought they were carefully 'filled and trimmed'. With extreme magnification, the front of all the claws showed me differently.
In this spectacular photo, you can even see that the claw is not fully touching the stone. In using your Optivisor or hand loupe of 10power magnification, all of these defects would be missed.
Here is a #002 round bur initiating to cut into the metal to make the mini claws. Can your loupes guide you in these circumstances?
Here is even a smaller round bur of #001 carving into the metal.
From a distance, there are a few (3) errors in the graver cuttings. You can see the results of the Milgrain design on the metal.
This is the printed description on every graver blade.
For your information, the actual length of the metal cutting is barely 3/8th of an inch. Again, all of these photos were using 600x power enlargement.
This is my 'bead-raiser' showing the gently curved front of the Onglette blade.
Normally the defects on the Cubic Zirconia wouldn't be seen, but with this Digital Microscope, every defect is easier to see.

This is one of the most difficult engraving samples in metal carving. The tool is the front of a #40, 'Flat graver' that I used as a reference for the size of the pattern.
I hope now that you can appreciate the powerful magnification of the microscope.
