About Precision Cut Calibrated Ruby Gemstones
Precision cut calibrated Ruby gemstones are
crafted to the most precise specifications and uniformed in terms of brilliance, colour, clarity,
dimensions and shape. To achieve such uniformity all precision cut gemstones are machine cut
using state-of-the-art automated cutting technology with digital precision of computerised
controls which guarantee the highest standards of quality control.
The size tolerance is ±0.03 MM, compare to normal hand-cut ±0.1 MM and
to ensure perfect balanced symmetry, we keep the depth average to 65% and the table size to 55%
of the stone dimensions.
