Laser Mapping of Concavities

Laser Mapping of Concavities

From the materials of Pricescope Diamond Journal "Lasers used in planning the cutting of diamonds" by Garry Holloway. All scanners build 3D virtual models by photographing the shadow profile of a rotating gem in front of a light source. But this method misses concavities (see the example in first im…

Scanning major and minor symmetry features

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 obt…
