These are all devices used by respected gemological laboratories, vendors and appraisers to arrive at precise measurements for all diamond proportions. Some grading reports do not provide every angle and measure but a Sarin report does. At Whiteflash we feel your investment is worth having such a machine onsite so that we can provide this information for you.
If a diamond has a GIA report prior to 2006 you can click on its Sarin report to get measurements not included on the GIA document. AGS documents have most of the angles and measures you may be interested in, but we still include the Sarin report run on our premises as further verification.
