Here you can find information about what is new in HP Carbon version 1.5.3.
Executive summary
There is continuing growth of interest in fancy diamonds in such specific markets like India and the West. It is expected that consumers in the key Asian markets will follow the trend quite soon. Our goal is giving our clients the opportunities not just to supply the new demand smartly but also to build robust long-term positions with development of their distinctive signature products in fancies in a very commercially efficient way.
With the current release we offer manufacturers a unique chance to consistently build all-company's in-house know-how to make best performing fancies with bigger yield. With every successful cut highly appreciated by sales team and consumers, the aggregated company’s knowledge expands and provides more winning options for the future cut searches. Important that starting from this release the models’ parameters are kept secret, so, nobody can copy them from your company’s database.
Before this release
Polishers always used available technologies and tools in the best possible way. The combination of Smart Recut, X-ray and Compass technologies provided great results for round shapes at the semi-polished stage because of the relatively limited number of parameters which describe an RBC.
The situation was quite different for fancies. The fancy shapes optimization algorithms provided solutions which were used to estimate Carat weight of future stones (to set target weight).
These solutions could not be effectively used as a direct Galahad plan for the following reasons:
Usually, polishers finally worked out how to get more out of the stones on the basis of the recommended solutions (deciding on Slopes and Azimuths of facets). They considered a certain Crown-Pavilion range around the centers of recommended solutions. So, the result (Diamond Carat Weight and Performance) significantly depended on polishers' skills: every polisher built his mastership, but this experience could be hardly used by other colleagues and was doubtful to become the company's long-term asset.
After this release
The new release offers a new format of fancy cut description/identification: it is possible now to change not just the height but also every separate angle. The models appear now in a “multilayer” mode, which allows to change every layer independently. This gives more freedom and potential to the search of the best performing proportions.
Successful models found by polishers or as results of in-house Cut Evolution projects are to be stored in an aggregated in-house database to be used in the future optimization searches. So, with every successful model company builds its expertise incrementally. Important that for the commercial security reason the saved models will be used by optimization algorithms only, they are protected in a way that they cannot be extracted from database as sets of parameters.
In-house cut appraisers define deviation ranges for selected successful in-house models. In this way company builds own multidimensional space of recommended models with corresponding appraisers. The natural selection process guided by choice of sales team and consumers results in survival of the best spices. No bad stock with high discounts anymore. The best cut pedigrees make up the golden fund of your company, its highly valuable intangible asset, which consistently brings tangible sales and orders. Your skillful polishers contribute to in-house database, but your company does not depend on every polisher so much anymore because their craftmanship is continuously accumulated for future in-house usage. Even novice polishers can deliver great results based on in-house stored expertise.
In-house cut allocation takes place in the following way:
After this apply all allocation forms to find the best solution for every Rough/Semi-polished stone and optimize within a range of parameters (including Crown slope and Pavilion slope in new introducing Goodwin type of cut) according to in-house cut appraisers.
Such optimization selects solutions with maximum mass and performance close to actual proportions that were already polished in-house and approved by the sales team. These solutions are designed for direct execution by Compass.
This approach provides company management and sales team with effective tools for directing and controlling polishers’ job in order to reach the lucrative market segments and avoid bad stock and huge discounts.
Start to maintain the cycle of continuous building and improvement of your company’s in-house incremental database right now. Every successfully polished stone secures future company’s position in this highly competitive market. Secure your market share with your signature in-house cuts.
Technical details
There are more detailed description of new important tools and features of the release:
To achieve excellent optical performance for in-house fancy shape cuts, it is necessary to control the Crown slope and Pavilion slope parameters, SweetLine parameter of your models.
Previously registered new in-house cuts could be only of ASCII type (limited set of parameters) - now you can select a new in-house cut to be of the Goodwin type. In addition to ASCII parameters, for such cuts, you will be able to control:
Below is an example of the benefits Goodwin type cut provides comparing to ASCII:
SR with ASCII produced bigger windows which makes them actually unacceptable. Goodwin model does not contain such windows due to control over angles. This is also reflected by metrics. |
See this example details in the Goodwin fancy color example article. |
To register your model as a new cut of Goodwin type:
In Plans & Scans, right-click the best normalization result* and then, from the context menu, select Register as new cut. The Register new cut dialog is displayed.
* Usually, the "1. High_Sym_CFM" Smart Normalize preset (magenta colored) provides a result most suitable for further registration as a cut. |
In the list, click the appropriate template.
Which template to choose?
Template | Description | Cut sample* |
---|---|---|
1C1P | For cuts having 1 tier for a pavilion. Allows controlling one angle of a crown (1C) and one angle of the pavilion (1P). The template is suitable for most cuts. | |
1C2P | For cuts having 2 tiers for a pavilion. Allows controlling one angle of a crown (1C) and two angles of the pavilion (2P). | |
2C3P | For rectangular cuts with 2 tiers for a pavilion. Allows controlling: * separately of two angles of a crown (2C) * three angles of the pavilion (3P): * two on the 1st tier of a pavilion * one on the 2nd tier of a pavilion |
* Note that if you have several "Main" groups on the same Tier but different SubType, the priorities are used to define which group will be controlled by the parameters.
(higher priority) EMPTY (lower priority) |
Goodwin type cuts support AnyCutBasic appraiser as well, but with the lack of important advantage of having slope angles in the appraiser.
Note that selecting a template is not enough - later you must edit profiles manually. |
Click Ok.
The new cut of the Goodwin type is created. It is added to the Diamond Allocation section, Cutbook > in-house Cuts. Also, from the selected template, a new hybrid appraiser is created for this new cut.
This is not the end, but just the beginning of the process. The next two "big steps" are obligatory to make your new cut/appraiser work effectively. The details about why it is important to populate a cut with the allocation forms and set your own boundaries for the linked hybrid appraiser you can find in the In-house cut registration, Hybrid appraisers, and related articles. |
Edit the boundaries of your appraiser profiles.
It is recommended to coordinate set boundaries of your appraiser with the allocation forms: |
During in-house cut registration program creates appraiser with parameter intervals from the selected template. Start allocation form which is used for cur registration could be out of EX group by some parameters.
There is new feature in software to adjust automatically intervals "Absolute Proportions" to set start allocation form in EX group that is required for correct work of further allocation.
The intervals adjustment is following: intervals from templates are shifted on the some value of parameters ("parallel shift" for parameter intervals of EX, VG, GD, ... groups). The value of the shift is found by software by such way that value of each parameter is exactly in the middle of EX group. Therefore all values of start allocation form are set in the middle of EX group. Intervals size [min, max] for each group are remained the same as in template.
Intervals before adjustment | Intervals after adjustment |

Cutwise online service integrated with HP Carbon allows quick sharing via the Internet information about polishing plans (solutions), including renderings of future stones, indistinguishable from the real DiBox2 films for both Round and Fancy cuttings. Now in addition to visual and parametric representation of plans, Cutwise is able to present solutions in 3D interactive space (like Scene in HP Carbon) - Carbon Viewer.
Thus, full information about plans ( parameters + media + interactive 3d model ) now can be easily shared with the remote team members (polishing experts, managers, sales specialists) or customers. The Carbon Viewer provides full and interactive information about:

When uploading from HP Carbon, ViBox, and DiBox to Cutwise, it is important to have data related to the same rough (its scan, solutions, final polished stones) within the same Cutwise project. See current recommendations and examples of how to achieve that in the article:
Now you can plot cavities manually on your model using the new Inclusions mode. To switch to the Inclusions mode, on the top panel, click Inclusions.
The following scenarios can be implemented in this mode:
See details in the sections below.
To plot cavities in live mode:
In the following description, 2 operators are acting - this is optional, all the activities described may be performed by the same operator. |
To plot cavities via photo sets:
To quickly prepare quality photo(s) of your rough:
There is option to change clarity or status of inclusions from scene by two clicks:
There is known issue that after change of clarity or status there is no update in Inclusions list: |
To add one more diamond to already created solution you can use algorithm "21. Next". The next diamond will be added in maximal possible free zone of rough volume which is not occupied by created before diamonds. A position of existing diamonds is not changed.
Important! Algorithm "21. Next" during work takes into account allocation forms of Cut that allows to find better solutions for in-house cuts. Note that algorithm Find Next Diamond in Helium Rough / Pacor Client doesn't work with many allocation forms so we recommend to use "21. Next" and HP Carbon to find next diamond.
Before run of algorithm please make sure that you select one or several solutions where you want to add one more diamond and cut types from Cutbook.
There is possible to create solutions composed of 2, 3, 4 and so so diamonds.
There is a sample of algorithm "21. Next" work:
0012_NextDiamond.ox2z
Sol. #40 contains 5 diamonds, it was allocated sequentially from sol. #24, 30, 34.
Currently some allocation algorithms exists only in Helium Rough/Pacor Client but not in HP Carbon. Mainly there are semi-automatic or manual algorithms, that are available in Tools mode (like "Fixed Diamond Weight", "Change cut" and so on).
Therefore the same project is need to be open in both programs (HP Carbon and HR/PC) and compatibility of cuts and appraisers is required for work convenience.
Previously registered in HP Carbon Cuts and linked Appraisers are automatically loaded to Helium Rough since version 7.4 if Helium Rough is installed on the same computer.
Hybrid Appraisers (with Absolute and Relative parts) has limited compatibility:
Helium Rough will allocate with the same conditions of hybrid appraiser like they was during exit from HP Carbon. Under conditions we mean absolute, relative parts and profile .
Example of work:
Suppose we have following list of in-house cuts in HP Carbon:
When we run Helium Rough then the same cuts will be available in panel Diamond.
To run allocation with in-house cuts it is required:
Auto Appraiser allows to run allocation with several cuts and their linked different appraisers.
Holder deterioration requires it's replacement sometimes to get correct results of scanning. Now this procedure is accessible for users with special "Alignment" license bought from supplier.
You can order brand-new holders from scanner supplier too.
A procedure of holder change is described in Manual about holder change.
To use this functionality all the conditions should be met:
|
There are price discount for cut quality groups defined in appraiser. Initial discount that we provide "from a box" may not correspond actual market demand and specific customer needs.
There is a new Discount tab to edit discounts for Cut Quality groups (EX, VG, GD etc.) in Appraiser Editor panel:
The change caused by Request |
To increase model symmetry and remove excess facets, you can use the Smart Normalize algorithm. Previously, if the model that you were going to normalize had mistakes in its facet types, Smart Normalize could provide non-symmetrical solutions. Now the algorithm is improved: it tries to fix mistakes in facet types and then provides excellent symmetry.
Hint This is especially useful when mistakes are not obvious to an operator.
Technical details:

In HP Carbon, plans for Brilliant cut are allocated with the "GIA Facetware + My Round" appraiser. GIA Facetware rounds the parameters' values.
In some cases, this rounding may cause a problem: when you finish cutting in precise accordance with the plan and the result is scanned, different scanners (for example, yours and GIA lab) may slightly deviate the scanned model. So if our plan was too close to rounding boundaries, the resulting parameter value after rounding may go outside the EX boundaries to VG, etc. This can cause your EX stone from your scanner perspective will unexpectedly become VG from the GIA lab perspective.
To eliminate this risk, for the Smart Recut algorithm, the new Safe Boundaries mode is added. It is intended to be used when working with Brilliant cut. The mode sets safe distances to a possible GIA rounding. The values are:
GRID Parameter | Margin | Units |
---|---|---|
Table | 0,008 | mm |
Crown angle | 0,10 | deg |
Pavilion angle | 0,06 | deg |
Star length | 1,5 | % |
Lower girdle length | 1,5 | % |
Girdle bezel | 0,1 | % |
|
Other GIA Cut parameters | Margin | Units |
---|---|---|
Girdle valley Min | 0,1 | % |
Girdle valley Max | 0,1 | % |
Culet | 0,1 | % |
Crown painting | 0,2 | deg |
Pav painting | 0,2 | deg |
Sum painting | 0,2 | deg |
At the moment, these values cannot be changed - in the future, it is planned to provide a user interface for viewing/editing. |
The mode is turned on by the Safe Boundaries checkbox.
The mode can be used when running the Smart Recut allocation from Recut solution. However, if you already have a Smart Recut solution previously obtained without using the Safe Boundaries option, it is more effective to run Smart Recut allocation with Safe Boundaries from this previous Smart Recut.
The Table parameter can obtain a value close to the GIA rounding boundary (for example, 58.49%). This means that regardless of rounding up or down (58% or 59%) the required GIA Cut Grade will be produced with the other 5 GRID parameters set. |
The below functionality is available only with product/license "FancyColor" bought from supplier and activated in your HASP key. |
There is a library of specially designed and optimized for enhanced fancy color performance Goodwin cuts:
Cushion_FC_RT1_1_EX_Oct2021G, Cushion_FC_RT1_2_EX_Oct2021G, Oval_FC_EX_Oct2021G, Pear_FC_EX_Oct2021G, Radiant_FC_EX_Sep2021G, Radiant_FC_RT_Oct2021G
Every cut in the library is packed with a protected set of allocation forms and preliminary tuned appraiser. Effective set of optimized allocation forms is especially important for fancy color diamond allocation.
Allocation of the Fancy Color diamonds has some additional important goals: better color intensity and distribution. These goals require the SmartRecut engine to be more fine and accurate when changing the initially color-optimized diamond form in order to avoid degrade of color performance. To settle this difference between color optimized and colorless allocation we need SmartRecut to operate on different set of settings known as "smart recut presets". The HP Carbon 1.4 has a new special set of smart recut presets for AnyCut Fancy Color diamond allocation which can be modified independently from the usual AnyCut presets which are used normally for colorless allocation. At the stage of the registration of new In-house cut operator can tell the program that the cut will be used for fancy color allocation, by ticking the "Fancy Color" option. So the SmartRecut will use the proper set of SmartRecut presets when dealing with "Fancy Color" ticked In-House cuts. The following illustration demonstrates this new option.
NB Please notice that the Cuts from OctoNus Fancy Color optimized cuts Library is already marked and will work with AnyCut Fancy Color SmartRecut presetes.
For your convenience and easy self-identification of your own optimized Fancy Color we recommend to add "_FC" symbols in the name of the In-House cuts, like Oval_FC_OtherProperties.. |
Since HP Carbon 1.4 you can use a mode for calculation pairs of parallel windows or "openings" required for absorption spectrum measurement.
There is "opening" button in the top toolbar:
The function of the Openings mode is similar to former "Oxygen DZ" software.
For the Rectangular and Square Cushion cuts the grades were added to the following reports:
Some minor layout changes were caused by this change (shorten parameter names and display positions.
Rectangular Cushion | Square Cushion |
---|---|
Information about the width, length, and girdle ratio is added to:
In previous versions, for in-house cuts the algorithm 19. SmartRecut (Brilliant, Oval, AnyCut) controlled only the azimuths symmetry of the facets. But a change in the absolute value of azimuths could lead to a big loss of the solutions performance.
Therefore two parameters have been added to control the tolerance of azimuths from the initial values. More "narrow" MainAzimuthsToleranceModule is tuned for only Main facets. Less "narrow" OtherAzimuthsToleranceModule is tuned for other facets.
For the stones with the fluorescence, for the Fancy diamond color estimation, you are now able to get the estimation corrected in accordance with the fluorescence effect level.
Correction can only be applied to the yellow diamonds with the blue fluorescence. |
The following fixes for the known problems and improvements are implemented:
Now you can view the first facet of the stone right in the Scene (marker is added).
Simple way to change inclusion clarity - now it is possible to change clarity from context menu in the scene.
1. Go to "Recut" mode. 2. Activate tool of inclusion selection in the main top menu of program. 3. Right click on inclusion and you will see context menu where you can tick clarity and optimization status (color of inclusion - green. yellow, red, grey) |
In Comparative I3D Mini View, for Average Parameters, some deltas were calculated incorrectly - now this is fixed.
In Facet Types, the way of displaying non-convex facets is fixed.
Before the fix, some problems with displaying of such facets could occur:
|
A perfect square cut has equal "Table along Width" and "Table along Length". Previously, only the "Table Widthwise" ("Table along Width") value was controlled in the appraiser "SquareCushion" by Absolute / Relative Proportions Table parameters. "Table Symmetry" parameter has been added to appraiser "SquareCushion" to control "Table along Length" value.
Algorithm Smart Normalize had different problems with Heart grooves. Algorithm Smart Normalize enhanced for Heart Cuts.
Example:
|
For projects with multi-diamond solutions, in the context menu of a scan, some items (for example, Processing Stage) were missing - now this is fixed.
Elements were missing when clicking on some cells.
|
Contrast of Inclusion (Faint, Slight, Medium, Dark, Very Dark) for visualization can be now specified in HP Carbon to have correct visualizations of Inclusions in photoreal in Carbon Viewer.
Improvement of refinement algorithm for building of models in HP Crown Reflect scanner. This improve the accuracy for some semi-RBC models.
In I3D Mini View Report now slopes of girdle facets are displayed in the range [0, 180] degrees. Before the range was [0, 90] degrees.
Slopes of other facet types are still displayed in the range [0, 90] degrees.
