PGCG (Presidium Gemstone Computer Gauge)

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

Presidium Gemstone Computer Gauge measures the dimensions and estimates the weight of loose and mounted gemstones with precision, speed, and ease. After entering the weight and the measurements of a gemstone, PGCG narrows its identity by computing its S.G. value.

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.
