Gemmological features and technology processing of kuntsytes

The main purpose of this work is to study the properties and chemical composition of kunzite from various deposits, as well as study the features of processing and the application in practice of the cutting techniques of two types: wedge and step, and thereby identify the best characteristics of the stone, such as color and dispersion. The comparative analysis is made on the example of samples of kunzites from the collection of the ANO "Gemological Institute" and the collection of Edward J. Gübelin, GIA.
