How to Adjust the Separation Value
Example images for rejected reason: Bad Searation
Below are actual images of scans that were rejected for 'Bad Separation'.
The images shown below were taken from our Quality Check process.
Following the images are instructions for setting the temporary separation value and setting the default separation value.
Separation refers to how the BrillianceScope Analyzer program determines the exact outline of the stone in the scan image, separating the gray background of the image square from the stone image itself.
An incorrect separation setting can cause either excess flaring around the perimeter of the stone (not enough separation) or may cause part of the stone image to be missing (too much separation).
This can usually be seen in all six Light Views.
Even when the default separation is set correctly, it may be necessary to temporarily adjust the separation setting for very small or very large stones.
Temporary separation settings will be reset to the default separation value when the BrillianceScope Analyzer program is closed and reopened.
When a scan has bad separation, it is recommended to adjust the separation value and rescan it before saving to prevent delays in getting an approval.
If a scan with bad separation is saved, and then the stone is rescanned and saved again, they may both be automatically rejected for 'Duplicate' without us ever seeing the scans in our Quality Check process if the scans are sent to us at the same time.
Important: After changing the separation value it is important to let the next scan finish completely before determining if the separation setting is correct.
Separation is not calculated until all of the images are captured.
The two examples below have too much separation.
Part of the image is missing.
The separation value must be set to a lower value (see instructions below):
The three examples below do not have enough separation.
There is excess flaring around the perimeter.
The separation value must be set to a higher value (see instructions below):
How to Adjust the Temporary Separation Value
Go Back to top | Go to 'How to adjust default separation'
- Open the BrillianceScope Analyzer program located on the desktop.
- Click "Setup".
- Change the separation value, then click OK (see diagram below).
Suggestion: Only make adjustments by one full number at a time (example: change 13.5 to 12.5).
Numbers may be set to one decimal place if necessary (example: 11.5, 11.4, 11.3, etc.).
This temporary change will remain until the program is closed.
- Test the change by scanning the diamond again.
Important: Let the next scan finish completely before determining if the separation setting is correct.
Separation is not calculated until all of the images are captured.
- Readjust the separation value again if necessary.
How to Adjust the Default Separation Value (permanent change)

- Get three different size diamonds to use for testing:
- 1/2 carat (50 point)
- 1/3 carat (33 point)
- 1 1/2 carat (150 point)
- Scan the 1/3 carat diamond.
- Raise the separation value (see Adjusting Temporary Separation) until it appears that part of the stone is eaten away (see above examples of scans where part of the image is missing).
It may require several scans to get to this point.
Let the next scan finish completely before determining if the separation setting is correct.
Separation is not calculated until all of the images are captured.
- At the point where part of the stone looks eaten away, lower the separation value by increments of 0.5 until the stone looks whole.
- Scan the 1 1/2 carat diamond.
- If the stone looks whole, scan the 1/2 carat diamond and verify that all three stones look whole.
If all three stones look whole, use this separation value to set as the 'default separation' value.
- If the stone looks partly eaten away, lower the separation value by increments of 0.5 until the stone looks whole, then scan the 1/3 carat and the 1/2 carat diamonds and make sure that they all look whole.
- Close the BrillianceScope Analyzer program.
- Open Windows Explorer
- If there is a 'My Computer' icon on the desktop, double-click (left mouse button) on the icon.
- If there is not a 'My Computer' icon, right-click on 'Start' (right mouse button), then click on 'Explore' (left mouse button).
- Navigate to C:\Brilliancescope\Startup.dat
- Double-click (left mouse button) on the C drive. This is usually shown as '(C:)' or 'Local Disk (C:)'
- Double-click (left mouse button) on the Brilliancescope folder.
- Double-click (left mouse button) on the Startup.dat file.
- Open Startup.dat with NOTEPAD.
- Scroll down to the Notepad icon and double-click (left mouse button) on it.
- Click OK (left mouse button).
- There are two different versions of the Startup.dat file. Identify which version is being used from the examples below and follow the steps for that example to make changes.
- Example for first version of Startup.dat (if this does not look the file on your computer, scroll down to the second example): At the bottom of the page change the number after "DefaultSeparation".
Numbers may be set to one decimal place if necessary (example: 8.3, 8.4, 8.5, etc.).
- Example for second version of Startup.dat (if this does not look the file on your computer, scroll up to the first example): At the bottom of the page change the number after "DefaultSeparation".
Numbers may be set to one decimal place if necessary (example: 11.5, 11.4, 11.3, etc.)
- Save the file with changes
- Click File, then click Save (left mouse button).
- Click File, then click Exit (left mouse button).
- Open the BrillianceScope Analyzer program (double-click the icon with the left mouse button) located on the desktop.
- Click the Setup icon (left mouse button) in the middle of the window.
- Verify the change was made, then Click OK (left mouse button).
- Test the change by scanning the diamond again.
Important: Let the next scan finish completely before determining if the separation setting is correct.
Separation is not calculated until all of the images are captured.
- Change the default separation value again if necessary.
