For the benefit of all those interested in cut quality and new developments, this is the text from this link.
http://www.eightstar.com/scope/
I would not dare post the images refered to - so look at the link yourself.
"These pictures were taken using Firescope technology. The diamonds in the top row were graded AGS 0 ideal cut. Picture number 5 has "excellent" symmetry according to the GIA. The truth about how a diamond is cut does not come from external dimensions and comparison to an ideal mathematical model. The last three diamonds are not very brilliant and you can see it instantly with Firescope technology.
The Firescope was invented in Japan after 7 years of research that began in 1977. It allowed the first look at a diamond''s brilliance and optical symmetry. It shows you instantly what gemological reports cannot about how a diamond is performing. It allows you to instantly determine how good or bad a diamond''s cut is.
Light from beneath the diamond strikes a red reflector and enters the crown from all angles above the girdle. Where you see white, light does not return through the crown (no brilliance). Light pink shows that light entered the diamond from low angles. Darker pink from medium angles. Red from higher angles and black from 80 to 90 degrees. Reflections from light pink to black, therefore, indicate brilliance. White is lost light return, lack of brilliance. The greater the optical symmetry, the more you can expect fire from the diamond.
You can use this technology to:
• Compare diamonds to each other instantly
• Purchase better diamonds faster than ever before
• Demonstrate the superiority of what you sell
• Improve your image as a professional
• Recover cost of device with one or two good buys
The SymmetriScope is made in America under the direction of Richard von Sternberg. Richard opened EightStar Diamond Company to cut EightStar diamonds in 1990 using the Firescope to guide and perfect the cutting. No person in the Western world enjoys Richard''s experience with this technology. Improvements have been made to the SymmetriScope that have tailored it to the American jewelry market. It has a stronger light source, is easily portable, is made with metal instead of only plastic and will accommodate larger diamonds than the Firescope. It was the goal of von Sternberg to put this superior instrument into the jewelry industry before a mass-marketed cheap imitation began to appear that might make inferior diamonds look the same as superior ones the way hearts and arrows viewers do.
Your customers can see more in the SymmetriScope than a master gemologist without one.
Hearts and arrows viewers only show you the main facets of the diamond, masking 2/3 of the stone. The SymmetriScope shows you EVERY facet of the diamond, illuminating for you the entire light path within each stone.
Hand held imitations now being marketed are inconsistent and unprofessional by comparison. Stones viewed in them must be held in tweezers and appear different depending on the color of the tweezers. They lack the exactness of the SymmetriScope, only allow you to view one diamond at a time and cannot, therefore, be used effectively to compare one to another.
What you get:
• SymmetriScope
• AC adapter (will also work with batteries)
• Easy to use manual showing what you see in diamonds, how to grade them optically
• Unconditional one year warranty
How much it costs:
• $1,200 (includes shipping)
