Scanning major and minor symmetry features

Major and minor symmetry features can be revealed by Helium precise 3D model, like pictured here naturals, not proper facet junction pointing, and «twist» or shift of the upper and lower girdle facets.

It distinguishes Helium scanner from other scanner models.

Photo of the diamond with 3D-model obtained on Helium scanner. Major and minor symmetry features are shown by red and yellow circles.
