Inconsistencies in "The French Blue and the Hope"
Letters  Gem & Gemology  Summer 2009

In their article presenting a new model of the French Blue (Spring G&G, pp. 4–19), Farges et al. used a newly discovered lead cast to confirm the possibility of the Hope diamond being cut from the French Blue. During their research, they created a three-dimensional model of the cast based on the shadow projections obtained by an Octonus Helium Rough 1:4 scanner operated by Matrix Diamond Technology. The dimensions of the model are 30.37 x 25.50 x 12.87 mm, which match those of the lead cast within 20 microns accuracy. (This model is available at www.octonus.com/oct/projects/frenchblue.phtml.)

From my analysis of the 3D model, I disagree with some of the statements made in the article...

Diamond Calculator 3.2 demo version

Vivid color demoYou may have tried to explain the benefits of DiamCalc to friends and associates. There is a powerful free demo version. It is available for download here.

The demo version contains three examples:

  • Marquise – parametric cut demo
  • Cushion – vivid color demo
  • Crack – inclusions demo

Crack inclusion demoThe Demo enables all HDR rendering features for the limited included examples.

Please read the detail descriptions of new possiblities and restrictions in the DiamCalc 3.2 Demo version.

Synthetic Appeal

Many diamantaires believe that synthetic diamonds pose a risk to consumer confidence — because "fakes" might be passed off unethically as natural diamonds — and that high-end consumers will never choose a synthetic diamond anyway. But what if man-made diamonds created their own new markets by developing a niche in exclusive luxury goods?

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 new features:

  • Added the possibility to generate same RTF and HTML reports for scanned polished diamonds as in the OctoNus Helium software. Users may customize report templates to fit their needs. Such reports may be generated using files with 3D model of the stone obtained by OctoNus scanners as well as using any other imported 3D model. There are examples of new DiamCalc reports for Helium and Sarin scanned polished brilliants.
  • Support for external cuts from DLL was added. All DLLs implementing such cuts should be placed in the "Cuttings" subfolder of DiamCalc. The content of this folder is analyzed at the start of the program and all found cuts are appended to the list of available cuts. If you save DMC file with external cut and pass it to another user of DiamCalc or GemAdviser, make sure that the recipient also has the corresponding DLL.
  • The Cut Quality estimation has new index: Dark zone mono. Calculation of Contrast is disabled.
  • Added "Lower facets length" parameter to Brilliant cut to measure lower girdle facets according to GIA and Sarin.

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.

Download External cut (ExtCutSample.zip, 25 Kb).

Diamond Cut Study

How studying the cut parameters of a diamond can help a manufacturer to increase the efficiency of his work and allow a dealer and jeweler to increase the price and liquidity of the diamond?

Take a look at the results of diamond cut studies carried out in MSU

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.
