Thread: Blue/Yellow Belgium? Or a Coticule?

I did some comparison shots of the BBW and the Rouge Du Salm.

Typical for the Salm is a reddish wine red coloration of the slurry. Also the stone itself appears more red then blue. Sometimes orange spots appear as visible on the first picture.

The polishing up the bevel in most cases appears much more fine and pronounced.

Sometimes white lines or white inclusions can appear:



Thats probably a good shot to see the differences quite easy...
