Diamond forums are packed with people asking for advice on princess cuts.  Sadly most of them are like the stone in this report.

Here at our place of business we have a formula and a system for picking and locating the finest and most brilliant princess cuts.  We will not disclose our method for doing so as we do not care for our competition to know our secrets; however, I will share one very basic rule with you here and it is the first step we take when beginning our search.

If you really don't care about how brilliant your diamond will be, then disregard the information on this page.

Our very first step to finding the best princess cuts is to NOT waste any time with stones that have tables that are larger or greater than their total depths.  This diamond serves as an excellent example of the hundreds we have analyzed in the past with similar proportions.

This diamond has a 67.6% depth with a 75.7% table.

Assuming you've already downloaded the Sarin Web Viewer, you can see the physical dimensions of this diamond along with a 3D model of the stone.

To view this diamond's Sarin analysis you'll need the Sarin Web Viewer which you can get at this link. You only need to download and install this once and you do need Microsoft Internet Explorer version 5.0 or higher.

After taking this scan of the diamond, we can then import this into the DiamCalc software and see how this stone performs with regard to its light return.  As you can see from the image, this diamond is a terrible leaker. All the white areas are indicative of leakage and represent a large majority of diamonds on the market today.  Were a supplier able to provide me with the proper Sarin analysis, I could make this judgment quite easily and know for sure that I do not want to waste my time or money with it.  Unfortunately for most, the technology used here is approximately a $20,000 investment, and very few suppliers and ever fewer retailers have the setup.

Since this diamond is actually here in my hands, I took an actual LightScope image of the stone itself.  It's amazing how similar the actual is to the simulated image.

To better understand LightScope technology and how we use it to pick our diamonds, it would be best to read our article on this page.

Haha... YES, this stone really isn't the best, and we'd never recommend it for a purchase.  Now here is something new we'll be featuring on our website in the upcoming months and that is what could properly be called "virtual comparisons".  With the technologies we have here in our lab, we are able to scan in a diamond like the one above, import the 3D model of the stone into the RayTrace software, and then export a file for a program called GemAdvisor which was developed at MSU and is FREE. :)  So ... grab the free software here ...Download GemAdviser

Then open up the file on the stone above...

PR105HI1GEM.gem

In the GemAdvisor software click on the "light bulb" and select either Disco Light (haha... Disco must still be alive in Russia) then click on the green play button.

Now to make a virtual comparison!  While you have that stone rocking in front of you, click on this file and open it up. :)  Do the same thing ... put it on the proper lighting then hit the green button.

Here's the link to the actual diamond and its stats. "Link". The gem file above is based on an actual scan of the diamond itself. Cool stuff. :)
