THE GEMEWIZARD BLOG

A common color language is key to avoiding communication breakdowns in the gem trade

It may be overstating the case to declare that the better color communication system that existed in the diamond trade was mainly responsible for the massive disparity in growth between the diamond and colored gemstone sectors, but it certainly is fair to state that it was a factor. It was for this reason that Gemewizard® publicly launched its GemeSquare™ computerized color coding and communications system in 2006.

COLOR ANALYSIS BY GEMEWIZARD


Analyzing tanzanite color using polarizing filters

A color that is rare in tanzanite is a green-violet mixture displayed as an unusual zoning within the crystal. After fashioning and polishing, due to the facets angles, the colors merge and produce a remarkable metallic color. A 6.31-carat emerald-cut tanzanite was brought to Gemewizard® for color analysis. It exhibited this fascinating phenomenon.
