In the first revolution, when the pointer travels from 0 to
0, it reads 0-10mm on the millimeter scale. At the same
time, it shows a direct carat conversion of 0.01-3.65ct on
the red carat conversion scale.
For example: Reading directly on the red scale, a round
brilliant cut diamond measuring 4mm diameter will have
an estimated weight of 0.23ct.
In the second revolution, it reads 10.1-20mm and a direct
carat conversion of 4.21-29.14 on the black color carat
conversion scale.
For example: Reading directly on the black scale, a round
brilliant cut diamond measuring 12mm diameter will have
an estimated weight of 6.29ct.
In the third revolution, the pointer will not go further after
23+mm, and it reads 20.1-23mm. No conversion was
provided for stones above 20mm.
The Range Indicator indicates each time the pointer
passes “0” 10mm or 20mm should be added to the
reading.
