Commoditization of Diamonds

Why are diamonds – the ultimate luxury product – losing out so badly to other luxury goods? Is it because other luxury industries (expensive cars, high fashion, yachts, etc,) are innovative with smart branding and customization?

Diamonds are evolving into a traditional business with little innovation.

Since the 1940’s "A Diamond is Forever" established diamonds as necessities. But now "diamond the luxury" has become "diamond the commodity". We need to change this perception and make diamonds individual and unique again ...

Computer modeling of gemstones for improvement of their color appearance

There are many cases when a better cut can reveal a better color of a gemstone, and many cases when a gemstone’s appearance has some flaws because of its cut. Unlike diamond, colored gemstones cutting allows for a lot more freedom. A cutter can choose among many shapes, facet patterns and proportion sets. The primary goal for a cutter is to achieve the best possible color and to reveal the potential of every piece of rough material. Because of the complicated nature of interaction between light and gemstone facets, every facet matters. Cutting mistakes can become evident only after the last facet is polished. Today many commercially available colored stones have various optical flaws in their appearance. That is why cutters are looking for a way to predict the optimal appearance of future gemstone’s ...

Trade-in old technology rough diamond scanners for new clarity planning scanners

Rapid technological change has caught Indian cutters sitting on old technology rough diamond scanners. OctoNus clarity planning scanners, M-Box™ and Helium™, have made old technology scanners redundant. However manufacturers cannot justify throwing their earlier investments on the scrap heap. But they face losing money to competitors who upgraded to the OctoNus technology that optimizes included rough. Those competitors can pay more for the rough, and with African beneficiation schemes, there is a shortage of bigger rough in the market...

Lexus and OctoNus are offering Indian manufacturers a 50% rebate on today’s current sale value for Sarin rough laser scanners based on a seven year depreciation schedule. This generous offer holds until the end of October 2007.

The OctoNus clients receive the possibility to use original parametric cuts created by themselves in the Pacor software.
This allows:

  1. to use the possibilities of the cut most flexibly and most completely.
  2. to create independently and protect your competitive advantage either during the work with new cuts or during the extended work with existing cuts. The cut libraries created by you will be available only to your operators.

You can extend the list of cuts with your original cut(s) using external cut module.
External cut module is a dynamic link library (DLL) that holds the geometry structure of one or several cuts and contains necessary geometrical calculations.
External cut DLL's should be placed in the "cuttings" folder. They may also be loaded within specific commands in configuration files.

If you want to create your own external cut DLL please download the ExtCutSample.zip package.
This package contains the detailed specifications and requirements to external cut dll along with the Pear cut sample.

Diamond Calculator

OctoNus Software has designed a new software product DiamCalc - "Diamond Calculator", which enables precise calculation of the diamond weight and determination of the proportions.

Diamond Calculator - is a system to model polished gemstones, which enables precise calculation of the weight and determination of the cut proportions. The real (photorealistic) image of a polished diamond created by the system 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. Necessary cut parameters can be obtained by comparison of the real diamond to a computer image.
