Any dealer actually in possession of the diamond being considered with a Sarin or OGI machine can provide full facet-by-facet evaluation of the diamond, we can provide it for any diamond in our inventory or any diamond which we bring in on behalf of a client for evaluation. The problem is that so many of the internet dealers don't bother to personally evaluate the diamonds that they offer for sale - they drop ship direct from their suppliers and so many of the suppliers don't even have Sarin or OGI machines... They run the stones down the hall to another dealer and who knows the last time the machine was calibrated or whether the diamond was clean when it was measured... So many of the "reports" we see don't even come close to the measurements displayed on the lab reports... The lab reports indicates that the diamond has a total depth of 60.3% and the "report" says it is 60.9% but here the client is wanting us to compare the diamond for them site unseen to ours (based solely on the numbers) because "it scored well on the HCA" - well, we have to ask - if the total depth is off, what makes people think the rest of the measurements are accurate? Hey, we can accept 60.2 or 60.4% but to be off 5/10th's of a percent is a good indicator that the rest of the measurements may be off as well... We see this so much that we've stopped buying diamonds from our suppliers based on their Sarin / OGI measurements - we make them send us the diamonds to be measured on our own machine and we send them back everything that we don't like... So please, pay attention to the measurements being produced by the machine in relationship with what is given for the diamond by the lab for total depth and table... It is a good indicator of whether the measurements for the crown angle and pavilion angle are accurate. If you want an accurate HCA score you need to begin with accurate measurements!
