About Precision Cut Gemstone Dozens
Our perfectly matched dozens of gemstones are a
result of sophisticated quality and color sorting and can be used for
watches, spectacles, writing instruments, and accessories.
All precision cut sapphires
and rubies are crafted to the most
precise specifications and uniformed in terms of brilliance,
color, clarity, dimensions and shape. To achieve such uniformity
all precision cut gems 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, compared to normal
hand-cut ±0.1 MM and to ensure perfect balanced symmetry,
depth average is 65% and the table size 55% of the stone dimensions.
For maximum brilliance, fire and sparkle, all stones are round diamond
cut ( 57 facets) and if you are a registered customer, you can request
a free cut quality assurance sample.
