Should buying diamond rough be considered less risky, then I've been reading, if one were to utilize a Sarin machine to see what the potential of the rough is?
To use a cross analogy - to play it safe, I made sure the diamond I purchased for my wife's diamond wedding ring was GIA graded, with papers, and serial number engraved.
If someone ventured to New York or Antwerp to pursue purchasing rough, would it be an insult to ask that the rough item/parcel be sent for Sarin mapping (at buyers expense) before payment?
Just curious, what does it cost to scan/map a 1.0 ct rough diamond at a Sarin service?

Brigitte, Thank you for your help. I also found this great youtube video which helps me almost answer my own question. Something tells me the scan with laser cutting is going to cost at least $19.95.

Well, as in the fabulous gemology world, a good new gem refractometer is at least $700.00, without the light, I assume that you are right for the price of this Sarin item.
Happy to learn that you have found what you were searching for.

Were you having coffee with my wife today? The answer to your question is because I'm putting the cart in front of the horse. But like you, GIA is in our backyard and I'm working on a gameplan. I.e. Their Distance Program. Thank you for the reality check though.

Hay Ezra, if you have never seen the back street deals in the diamond world let me enlighten you to a few things i have seen. at least in the modern country's.
There is an honor system that is not spoken about with sight holders, they sell 100,000 of stones each year and a sight is by invite only. If a sight holder gets a bad reputation by doing shady deals, they are un-invited for eternity! Believe me when i say word travels fast to. there evaluation on stones from SI1 to I3 may be interpreted as a slightly worse or better grade depending on the grader, More than likely there VS2 to IF stones are spot on. As a small fish in a very large commercial pool, you will probly buy from a sight holder your self.
If you are buying in one of the gem producing 3rd world country's, then all bets are off and you BETTER know your stuff and then some. There are so many warnings i could never list them all.
There are however alternatives, Australia's diamond mines and Canada's diamond mines are independent from De-beers/Batswana limited, or you could adventure to Arkansas and mine a few your self.
No matter if it is colored stones or diamonds, i always recommend GIA to anyone buying rough stones either as a hobby or profession due to the wisdom and confidence you gain and are able to use when buying stones.

May I also point out that there is no shortage of diamond dealers, many of which are 3rd and 4th generation, with extensive experience, who are currently struggling to make a profit.
PS The GIA doesn't really train one to buy rough...more identify fashioned gems.

What is that phrase they say after they make a deal and shake hands?

Regardless of, and all due respect of, the integrity of Mazel. From my readings, it is almost impossible to determine the core of the rough even for the best diamond expert. So take the rough from speculation to the investment/business category with the sarin/sardine map.
