ImaGem Inc. launched Varna-D, a portable device for color grading polished diamonds. Weighing only half a pound and about the size of a weighing scale, Varna-D was designed and built with the members of the diamond trade in mind, as they require accessible and easy to handle tools for accurate and repeatable grading of loose diamonds.
The company said its color grading technology was developed and successfully tested to color grade diamonds of various sizes, shapes, fluorescence, zoning and secondary hues. It argues no this has not been accomplished successfully by any device introduced in the market.
Varna-D is configured for diamonds ranging in size from 0.25 carat to five carats. The color range covers D-L colors.
