A pre-purchase, screening tool for the consumer. An explanation tool for the appraiser.
Intended to gauge the credibility of represented color, clarity and cut grades compared to GIA or AGSL grading.
Highest Confidence: SCORE = 1
The grade will exactly match GIA/AGS 65% to 70% of the time. This is about the level at which these lab’s own graders match each other’s grades while working on diamonds. This grade ONLY applies to loose diamonds. Only very highly experienced, properly trained and equipped graders can claim this level of confidence. Very few gem laboratories or gemologists actually have this degree of competence.

When one looks for solutions to problems it is best to look for the simplest possible one. There may be more than one legitimate way to solve a problem or to accomplish a task, but the simplest method that does the job correctly is the one to ultimately choose. It is not wrong to try various methods, but when it comes time to adopt a standard approach to universally solve a certain problem or task, then the simplest method that provides the best results or equivalent results must be preferable.

The diamond business is at a moment in time where old ideas and technology are truly meeting head on. We have the GIA and AGS about to grade the cut of a diamond based on measurements and ray tracing computations along with minor parametric grade limiting characteristics. We have several other players grading or about to grade with similar technologies. We have Gemex using six light positions in an additive way that does not mimic real world lighting and some other tools which compare data with appearance.

I know there is an atmosphere of fear concerning Pricescope apparent in some of the postings on Polygon. Now, this is not universal, as occasionally someone will post that they have decided to participate with Pricescope. Many diamond vendors on Polygon do list their merchandise in many places on the Internet anyway. They just remain mum on the issue. What can they say that would be welcomed? They can’t win in this. They need to turn goods rapidly, as the profits are so short.

How did I get here and how do I get finished with it without going to my attorney?

Are you in a situation where you made a purchase, had a piece of jewelry break, a diamond chip, a stone get lost, or some other issue with a jewelry purchase or a vendor problem? Do you feel like it’s you against the entire industry? Do you, as a vendor, feel fearful of an unhappy customer and wish to make a fair settlement, but just can’t seem to come to an agreement? Do you have a damage or loss claim which is creating a problem because you may not have the correct insurance coverage? Is your replacement stone or jewelry a fair replacement?
