Presidium Gem Computer Gauge

A convenient digital gauge that measures actual gemstone dimensions and estimates gemstone weight and identity.

The Presidium Gem Computer Gauge (PGCG) is extremely useful For identifying unknown stones simply by measuring them. The SG (specific gravity) is automatically calculated from the dimensions and a list of gemstones with that SG measurement is presented.

• Can identify 74 different gemstones in 9 different shapes
• It is the only gauge in the industry that can give a direct estimation of the weight of various gemstones of a range of 9 popular cuts
• Gives users the convenience of not having to dismount their gemstones from its jewellery settings
• Suitable to use with loose and mounted stones with open back settings and is supplied with a high-setting attachment
   
• After entering the weight and the measurements of a gemstone, the Gem Computer Gauge is alternatively also able to be used to estimate the identity of the gemstone, by computing its S.G. value and referencing the internal stored database.
   
• With PGCG’s computer interfacing, gemstone measurement records can be easily imported and printed
• PGCG also comes with a CD-ROM that lists the S.G. value, R.I. value, and hardness measurements of 133 common gemstones in the market for handy reference
• Also includes touch button zeroing, a low battery indicator and comes with Presidium's Gemstone Weight Estimation Table which corresponds mm to carat and a protective case with an auto-magnetic power-off function
