IT'S USE: AKA: a "Proportion Analyzer" A Sarin Report is a page full of numbers detailing (somewhat accurately, and depending on the person operating the machine, the calibration and the specific program) the details of the stone in measured milimeters and angles. It is capable of measuring the different parts of the diamonds accurately to within 2 to 4 hundredths of a millimeter It is most accurate with round stones that can be spun around in the machine and be measured properly. It determines the accurate measurements of a stone such as: Shape, Weight, Width, Length, L/W ratio, Total Depth, Pavillion Depth, Pavillion Angle, Crown Height, Crown Angle, Table Size, Girdle, etc. These are just some of the few items in a Sarin report. Another machine that does the same thing is called a Mega Scope, which is just another company that measures a diamond by the same technique. HOW IT WORKS: It is usually a little black machine connected to a computer. It is a box-like structure with a sliding door where it has a little diamond holder where you place the perfectly clean diamond. You close the little sliding door and allow the machine to run laser beams throughout the diamond to determine it's size, shape and measurements. You must help the machine by entering into the program the general shape of the stone and this all produced several images of the stone on the screen. A photorealistic view, a 3D view, and also a video view of the actual diamond. OTHER USES: Some features allow you to even see what a recutting of this stone will look like into different shapes, and will approximate the loss of the cut for each shape. It is mainly used to allows the consumer to compare how well cut a diamond is in relation to the ideal cut proportions for a diamond. For more info and fun, visit Sarin online at: http://www.sarin.com/index.asp All the pros out there with Sarins, PLEASE chime in and enlighten us with some facts of the machine...seeing as there are only 20 Sarins out there in the world...

there are no lasers N. Just a white screen behind the stone and a video camera. the angles etc are worked out from the sillohette. Garry Holloway FGAA DipDT |

---------------- This sounds really basic. Has anyone worked out the emasurement error from this thing? With the HCA going all over the place for half a degree, one woudl need the respective error to get as small as 9'... to avoid adjusting for it. Oh well...

The Sarin I saw had a red low powered laser beam that went throughout the spot where the diamond stood. Hmm... I think the version they could have had was this one: http://www.sarin.com/diamark.asp But then the laser does not measure, it is used for marking. Thanks for the correction!
