4 Armed Dia Gauge- Carat Sizes

Compact and made from metal, the 4 arms fan out to
reveal varying sized holes each of which relate to a
carat size and are marked accordingly.
The appropriate sized hole is placed over the stone and
an indication of the stone size/weight is obtained.
These gauges may also be used to suggest what size stone
a setting will accomodate. The gauge is placed over the
setting and each hole is placed across the top until the
nearest size is reached.
