^{This GIA Graded Princess (square modified brilliant) cut diamond weighs 1.25 carats and is of VVS-2 in clarity and H color with inert fluorescence and has Excellent polish and symmetry which is the highest grade available from the GIA Laboratory.  Scan down the page for additional details and clarity photographs.}

The primary inclusions consist of a needle shaped diamond crystal as indicated in the upper region of the table facet on the plotting diagram.  There are also three tiny pinpoint size diamond crystals located on the underside of the diamond as indicated within the lower girdle facet in the 10 o'clock region of the lower plotting diagram... Good luck finding those, we practically burned our eyes out looking for those and we were using a lab scope.  There is also an "indented natural" located in the lower right tip of the diamond as indicated on the upper plotting diagram and an extra facet located in the upper right tip of the diamond as indicated on the lower plotting diagram, both of which are common inclusion types for princess cut diamonds and are of no concern.  Refer to our page on clarity characteristics for additional descriptions for these types of inclusions.  Sarin DiaMension computerized proportions analysis confirms that the proportions of the diamond are within the range for the zero ideal cut rating, refer to this document for an explanation of how to interpret the results of the proportions analysis.

For a really detailed view of the proportions and facet structure of this diamond, check out the 3D model for this diamond by clicking on the Sarin DiaVision icon pictured above.  Note that you will need to download the Sarin Viewer from Sarin Technologies and install it on your system and that you can view only one Sarin DiaVision file on your computer at a time, you will need to close one file to view another.

Although there is very little data in the Gem Ex Brilliance Scope Light Return Analysis database to provide comparative scoring for Princess cut diamonds, we provide an analysis anyway just because we figure that it is better to do so than to not...  It should be noted however that the machine is not intended to measure the light return for this shape of diamond at this point in time...  The scan indicates that the diamond exhibits a medium degree of Brilliance and a high degree of Dispersion with a medium degree of Scintillation.  Brilliance is reflected white light or white sparkle.  Dispersion is reflected colored light or what is frequently referred to as fire.  Scintillation is the reflected light which is observed from the stone when you or the diamond is moving.  Note that it takes approximately 3 - 5 working days from the moment we scan a diamond to the point when Gem Ex approves the scan and issues the graphic file that demonstrates the light return analysis visually, that file will be added to this page upon receipt from Gem Ex.

This is how the diamond "faces up" as seen through our Gem Scope, the primary inclusions are not visible at this focal depth.

This is how the table facet appears as seen through our Gem Scope using a normal light source, the small needle shaped diamond crystal is not visible at this focal depth.  We diffused the light in the second photograph to provide you with a different perspective of the region.  The third and fourth images are extreme close-up's of the diamond crystal as seen through our Gem Scope using normal and diffused light, the inclusion is not clearly visible using a normal light source, but can barely be seen using the diffused light source.  Needle shaped diamond crystals can be difficult to locate because they are extremely small and thin and tend to be translucent as one might expect from diamond crystal...

This is an extreme close-up of the indented natural located in the tip of the diamond as indicated in the lower right corner of the upper plotting diagram.  An indented natural is simply an indented portion of the original skin of the diamond, it was probably left on by the cutter so that the tip of the diamond would not be fractured during the cutting process.  This type of inclusion is quite common in princess cut diamonds and in the tips of other fancy shape diamonds.  We diffused the light in the second photograph to provide you with a different perspective of the inclusion.

The Gem Ex Brilliance Scope Light Return Analysis indicates that the diamond exhibits a Medium degree of Brilliance and a High degree of Dispersion with a Medium degree of Scintillation.  Brilliance is reflected white light or white sparkle.  Dispersion is reflected colored light or what is frequently referred to as fire.  Scintillation is the reflected light which is observed from the stone when you or the diamond is moving.  Note that it takes approximately 3 - 5 working days from the moment we scan a diamond to the point when Gem Ex approves the scan and issues the graphic file that demonstrates the light return analysis visually, that file will be added to this page upon receipt from Gem Ex.

"DiamCalc" Computerized Mathematical Ray Tracing Analysis:

The DiamCalc program simulates the probable paths of light return based upon the proportions of the diamond as determined by the OGI Mega Scope.  The estimated paths of light return and the estimated percentages of light return or leakage for each beam of light do not remain constant...  Rather they change appropriately as the axis of the diamond is rotated and refer to a specific beam of light and not the overall visual effect...  Thus if there are indications of light leakage, those percentages refer only to a specific beam of light as portrayed passing through the stone at a specific angle and do not indicate "overall light leakage" values for the stone...  Leakage can thus be mathematically "eliminated" simply by rotating the axis of the stone, so the bottom line is don't get too caught up in the "meaning" of these images, we just post them because they're kind of cool and we realize that you would probably rather have access to them than not...  The reality however is that we only buy diamonds that impress us visually for our inventory, we don't rely on the results of this program as part of our selection process because we insist on personally evaluating every diamond that we represent to guarantee that it meets our personal selection criteria.

This is a DiamCalc computerized simulation of what the diamond might look like when viewed through a Fire Scope (a.k.a. SymmetriScope)  The white areas within the image supposedly indicates light leakage within the stone, however we've never seen a diamond that does not exhibit similar amounts of light leakage so we do not consider this to be a concern...  For additional information on this concept, read about the SymmetriScope what we use in the store during our selection process.
