^{This GIA Graded Princess (square modified brilliant) cut diamond weighs 1.40 carats and is of SI-1 in clarity and F 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 group of pinpoint size diamond crystals which is commonly referred to as a "cloud" located in the center of the table facet along with a few rounded diamond crystals and short, thin diamond crystals called needles.  There is an extremely small feather located in the lower right corner of the diamond and two "naturals" which are part of the original skin of the diamond located in the lower left corner of the diamond as indicated on the upper plotting diagram and in the upper left corner of the lower plotting diagram and an extra facet as indicated in the upper right corner of the lower plotting diagram.  The extra facet is exactly what it sounds like, an extra facet that was added to the diamond probably to remove an inclusion from the surface area of the tip...  Extra facets are quite common on fancy shape diamonds and are no big deal...  Refer to our page on clarity characteristics for additional details pertaining to these types of inclusions.  Sarin DiaMension computerized proportions analysis provides the crown height and pavilion depth measurements, 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.

The Gem Ex Brilliance Scope Light Return Analysis indicates that the diamond exhibits a Very High degree of Brilliance with Very High Dispersion with a High 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.  It should be noted that there are very few princess cut diamonds in the Gem Ex database at this time for the comparative scoring to be based upon so the scoring results for princess cut diamonds will not be as accurate nor as high as rounds...

This is how the diamond "faces up" as seen through our Gem Scope, the cloud of diamond crystals is visible at this focal depth as indicated by the red arrows in the second picture...  These are essentially smaller diamond crystals which were trapped within a larger diamond crystal as it formed.

This is how the table facet appears as seen through our Gem Scope using a normal light source, the formation of diamond crystals is outlined by the red arrows.  We diffused the light in the second photograph to provide you with a different perspective of the inclusions.  The third and fourth images are extreme close-up's as seen through our Gem Scope using normal and diffused light.

This is an extreme close-up of the minute feather indicated in the lower right corner of the upper plotting diagram.  We diffused the light in the second photograph to provide you with a different perspective of the inclusion.

This is a close-up of the "natural" located in the lower left tip of the diamond as indicated in the lower left corner of the upper plotting diagram.  Remember that a "natural" is simply part of the original skin of the diamond which was left on during the cutting process.  Naturals are quite common in the tips of princess cut diamonds where the cutters try not to shave too deeply into the crystal so that they don't accidentally break off or splinter the tips...  We diffused the light in the second photograph to provide you with a different perspective of the inclusion.

To view the virtual model for this diamond using the GemAdvisor software developed by Moscow State University in Russia, you must Download this Free Software from MSU and install it on your system.  Open the DiaCalc Program via the Programs Section on your computer and then click on the icon above to run the file.

"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.
