The Centre for Gemological Analysis Masterstones is a modern laboratory equipped with advanced tools aimed at evaluating all parameters concerning cutting ratios and symmetry.
Software DiaMention
DiaVision software
The software for the analysis and classification of diamonds cutting is used by the main gemological laboratories in the world. It measures and classifies in a few seconds differently shaped diamonds, implements the most updated evaluation criteria used in the main rule laboratories and elaborates gems cutting evaluating the loss of weight. All data are collected in an SQL database and can be consulted when needed.
Proporziometro Sarin DiaMention
DiaMention proportiometer
Ultra tested, it has been sold since 1994, its tradition makes it matchless. A high resolution video camera and the inter changeable lenses offers a measurement field ranging from 1 to 28 mm. The accuracy is +/- 0,02 mm for linear measurement and +/- 0,2° for angular measurement.
Proporziometro Sarin SPlus
Sarin SPlus Proportiometer
Light and solid, it is used in the most intensive working moments as a replacement for DiaMention. It offers the same precision as the elder one, with a reduced measurement range. This tool is used for the outside analysis, such as the safety cases opening.
GIA Proportionscope
GIA Profile projection proportiometer
It is the ancestor of electronic proportiometers and is still used by the Center of Analysis for gems with extraordinary caliber, over 15 cts.
