Valuation of South African Ideal cut diamond

[catriona2105]

My husband recently returned from a business trip in Johannesburg and came back with a lovely birthday present for me..an ideal cut diamond!

I'm looking to get it valued and am wondering if anyone here can tell me if he got it for a good price or not.
It's a 0.43ct, VS1 clarity and the colour G diamond.

If anyone can help me with an approximate price, I'd very much appreciate it. Let me know if I have to provide you with any other information.

Many thanks

Hello. One man's G is another man's H. The definition of "ideal cut" also greatly varies because these are all really just opinions. And opinions on these matters vary quite a bit so when judging value of a diamond, the reputation of the grader is very important. If it's a GIA or AGS stone there is no question on it's accuracy. If it's EGL USA it can still be graded very accurately, other EGL labs or some international labs, or the opinions of the dealer who sold the stone is always questionable so that's just something to keep in mind.

Let's assume your stone is GIA graded, I would assume a fair price would be in the $900-1200 range.

I hope that helps.

Without being terribly argumentative, I must disagree. Since the turn of the last century the Diamond Trade has generally accepted the CUT parameters set down by Marcel Tolkosky. These are discussed on the web ad nauseam. Fundamentally the geometry of the subject diamond must conform to certain physical parameters that predestine the track of a light ray entering the crown and it's paths through the interior of the subject and ultimately back to the viewers eye.
