Hi all

My partner and I have FINALLY decided on the setting for our engagement ring. We're getting the Tiffany setting with a princess cut diamond, but we'll probably take a bit of the knife edge off the band.

We are going to be buying our diamond online and then having the ring made by a jeweller that has been recommended to us time and time again. As a result, we will need to purchase from www.jogiadiamonds.com.au the best cut diamond we can find.

Trouble is - I have no idea. I want as large a diamond as possible, to H colour, SI2 clarity, but I wouldn't know which ones are cut well. We are looking from .8 to 1ct.

Could anyone tell me what are the IDEAL proportions for a diamond of this size? Length, width, girdle, etc.E.g., If I see a diamond that is 5.2mm x 5.2mm across, then ideally how many mm deep should it be???

Thanks for all of your help.

Ask Jogia if they stock AGS0 cut grade Princess, that might be the easiest way,  and if they can supply ASET images and photos of the diamonds.  There really isn't a numerical formula which will get you a well cut Princess, you can use this chart as a guide but images such as ASET and detailed photos are the way to properly judge a Princess.  Look for a diamond with the table less than the depth, avoid girdle extremes such as very thin to thick, very thick etc and and get images from there.  Also if looking at SI2 clarity make sure someone can inspect the diamond for you and tell you if it is eyeclean to your standards or not.

Also as you are in Australia, check out www.hollowaydiamonds.com  and see what Garry can come up with for you.

This page explains about ASET and Idealscope images.

Nothing is more sacred as the bond between horse and rider...no other creature can ever become so emotionally close to a human as a horse. When a horse dies, the memory lives on because an enormous part of his owner's heart, soul, very existence dies also...but that can never be laid to rest, it is not meant to be...

What Lorelei said, or, if you want to give us a budget for the stone, we'd be glad to help you find one!

"It is also important for the State to inculcate in its subjects an aversion to any 'conspiracy theory of history' for a search for 'conspiracies' means a search for motives and an attribution of responsibility for historical misdeeds."

-Murray N. Rothbard, in The Anatomy of the State



John Swinton [1829-1901] Chief Editorial Writer of the New York Times (Considered "the Dean of his Profession" by his peers), when asked to toast an 'Independent Press' in a gathering at the National Press Club, circa 1880

"There is no such thing in America as an independent press unless it is in the country towns. You know it, and I know it. There is not one of you who dare express an honest opinion. If you express it you know beforehand that it would never appear in print. I am paid... for keeping my honest opinions out of the paper I am connected with. Others of you are paid similar salaries for doing similar things....

The business of the New York journalist is to distort the truth, to lie outright, to pervert, to vilify, to fawn at the feet of Mammon, and sell his country and race for his daily bread, or for what is about the same thing, his salary. You know this, and I know it and what foolery to be toasting an 'independent press.' We are tools, and the vassals of rich men behind the scenes. We are jumping-jacks. They pull the strings and we dance. Our time, our talents, our lives, our possibilities, all are the property of other men. We are intellectual prostitutes."

Check out their crossfire stones. They are usually AGS0 with ASET images and video.
