The DiamondView ™ is designed to look at any stones that have been referred by DiamondSure™.
The instrument looks at the surface fluorescence by illuminating with short-wave ultra-violet light. An image of this fluorescence is then viewed on a screen and a decision can then be made on whether the stone is natural or synthetic. Please see examples overleaf.
The colour of the fluorescence, the fluorescence pattern and the absence or presence of phosphorescence will differ depending on the stones natural or synthetic origin.
Loose polished stones can be viewed using the integrated vacuum holder although it is also possible to look at some mounted goods by changing the holder assembly.
