What is GemCalc
GemCalc is modern breakthrough computer software to model polished
gemstones, which enables the precise calculation of the weight and
determination of the cut proportions.
The program also creates the real (photo-real) image of a polished
diamond on the basis of the ray-tracing modeling. GemCalc makes
it possible to determine the cut parameters that cannot be measured
directly and to select the optimal combination of the parameters
to obtain the best perception (luster, brilliance, fire) of the
stone.
The optimal lighting environment for the best viewing of a certain
gemstone (say in a shop) can be easily developed with the help of
lighting design menu of the program.
At the top of mentioned above capabilities GemCalc allows to select
the arbitrary refractive index and color, allowing simulating any
polished gemstones.
Who benefits from it
GemCalc dramatically increases the efficiency of operations in different areas of jewelry industry and trade:
Cutting: An unlimited number of cut options of a stone can
be assessed in terms of gem appearance and key parameters with very
high efficiency before the stone is actually cut. This will help
to reveal the very best of a gemstone beauty, attractiveness and
weight, therefore make the stuff more competitive in the current
market.
Trading: The clients are getting nowadays more knowledge about gemstone
features and performance, looking for something really worth their
money. GemCalc gives an opportunity to present a clear visual
enlarged demonstration on gem appearance and properties to a consumer
and help to justify the quality, uniqueness and value of the stone,
which did attract your client. The demonstration and well-grounded
explanations very often support a person's desire to buy.
A photo realistic movie of the gemstone tilting in a variety of
directions produced by GemCalc can be used as a consumer's eye
grabber, if it is played on a computer, which display is set up
on a jewelry store counter or in a shop window.
Training / Education: GemCalc software can be used for both on campus and distance education
for those who are preparing to become the experts in virtually
all areas of the jewelry business, like cutting, jewelry design,
trading, etc.
The maze of a gemstone beauty and value dependence on the gemstone
properties and cut parameters quickly becomes much more understandable
for those who invested some time in working with GemCalc. This
tool combines in-depth scientific knowledge of gem and cut properties
and breakthrough achievements in computer sciences with extraordinary
Òeasy going interface.
The list of classic topics can be learned on an interactive way with the help of GemCalc:
- Study most popular cut shapes and visit the libraries of
unusual ones;
- Discover how the gem properties like refractive index, dispersion,
absorption spectrum, optic axes, double refractive, different
types of pleochroism, polarization, etc. impact the way gem
looks;
- Understand how the cut parameters influence the appearance
of the stone and challenge the current recommendations on
cut angles at absolutely no expense on spoilt specimen;
|
|
- Study the ray tracing in cut stone;
- Find out how differently gem looks under different lighting conditions;
- Master the modern cutting process by using the advanced reference database on gemstone features and photo realistic modeling of the final product before the stone is cut.

Main features
GemCalc is expressly sharpened for the work with color gemstones and gives unique power for:
Consider different types of gemstones (with different refractive index (RI) and dispersion)
GemCalc allows to work not just with diamonds (as DiamCalc
did) but also perform the calculations and get photo-realistic
images of the different gemstones, like sapphire, ruby, emerald,
tanzanite, garnet, etc. The type of gemstone can by selected
from the list of more than 20 most popular gem materials,
provided by GemCalc (this list will be extended). In this
case the standard parameters of the stone (RI, dispersion,
etc.) are downloaded for the calculations. Besides this, the
user has the opportunity to change manually gem material characters
according to external information available about a certain
stone. There is also a possibility to create his own new stuff
with optional figures for RI and dispersion. The average figures
for RI and dispersion can be used as well as spectral distribution
for RI.
Bring in different hues, tones and saturation
This option provides the user with a choice of different hues,
tones and saturation of the selected stone. They can be either
picked up from the list of the prevailing gem colors, provided
by GemCalc, or specified by absorption spectrum on the basis of
the external information available (for example, the spectrometer
data).
Review lighting conditions
Color change effect like demonstrated by Alexandrite can be modeled
by GemCalc. The user has the opportunity to review the gem appearance
choosing the light sources with different spectrums, like sunlight,
daylight, daylight lamp or incandescent lamp light. These light
sources are usually considered as white light sources, however,
each of them gives a certain hue to the stone color.

Take into account a color adaptation of a human eye
GemCalc allows seeing the appearance of the gems, which are lighted
with the source that is different to what a human eye is adapted
to. For example, how the client will see the color gems at the
jewelry shop window if the gems are lighted with quartz-halogen
bulb and the client's eyes are adapted to the sunlight? Just challenge
GemCalc to get the answer!
Pick up new fancy cuts and create new ones
External libraries for fancy cuts can be used for downloading
into GemCalc. For example, we would refer to the GemCad cut
list. If you want to load fancy cuts from other sources please
contact our service for assistance. There is also an option
to develop a new cut within GemCad software and import the
cut into the GemCalc program. Then GemCalc gives you the possibility
to examine the overall appearance of your creature and perform
the fine tuning of the cut to get the best appearance.
Dramatically reduce your time for calculations and reference search
Apart from the breakthrough possibilities provided to you by GemCalc
and described above, it also supplies you with a user-friendly
comprehensive reference database of gem materials properties (specific
gravity, RI, absorption, etc.) and cut parameters worth half a
dozen of dusty folios, which strive to shut immediately when you
just turn away.
