Went and had my diamond checked out by the Rockdoc very nice guy you can tell he is very bright in his field , very educational experience at first glance his office looks like some kind of diamond lab with all kinds of measurment stuff (if you go to an eye doctors office you will get an Idea of what I mean but add more) tons of stuff and reference materials,books, law books, measuring hardware, etc.. very interesting looks like the kind of place someone who really is into the trade. you really get a heck of a checkout he spent about 3 hours looking at the diamond with a finetooth comb he explains the process as he goes along and lets you see what he sees through the microscopes and other viewers. he is very careful to insure things are good measurement wise, calibrating the equipment checking and cleaning the diamond lots of times to insure and keeps all the documentation and stuff related to the diamond in its own protected container Anyhow if I explained all the details it would be a multi page post but in summary he is extremley detailed in the process and really takes his time looking at the rock the full reports are 30 whole pages I never seen such a detailed document but its pretty nice. I would definately recommend him, if you really want to insure things are okay and for the price you can beat the level and quality of service you get.
