Hey guys what do you all think about this stone? We are finally ready to buy and are looking like crazy but now that the process is really happening is kinda freaking me out to choose a stone. So i need your help. Share your outmost opinion on it. I was told by the vendor that is completely eye clean and sparkles like crazy. It is to be set in a platinum 3 stone setting. here is the cert. hope it works.

Thanks for posting this, I''m sorry I couldn''t read it.


Well, it''s not a bad stone...but I think you can find a little better. The HCA gave it a 2.3 VG/VG/VG/VG "worth buying if the price is right"

It''s probably a lovely stone, but for my taste is a *tad* on the deep side and there are better performers out there.

Here''s an .84 J/SI that I like a little better:
http://www.jamesallen.com/diamond.asp?cid=131&item=1027727

Here''s a nice one I/VS2 that is slightly smaller in carat weight, but only faces up a little smaller. I would ask about the VT-T girdle though.

This .77 J/VS2 is gorgeous:

This .81 I/SI2 is also gorgeous and faces up about the same as the one you posted:

Another I like:

This one might be out of budget, but it''s also nice:

I like to see depths between 60-62 and tables between 54-57. You can still have great performers with a depth over 62, but you are loosing spread at this point.

I would be more concerned with the crown and pavillion angles, this diamond is what is known as a steep/deep and might lose some performance because of it, I would keep looking.

Sorry - I should have been more specific. What we mean by a steep deep diamond is that the crown angle is too steep along with a deep pavillion angle. This can have the effect of causing some light leakage or a dark area under the table of the diamond to some observers. Try a search for ' ring of death' which is often used to describe this effect. Not all steep deep combos are unattractive however, but an expert here once said as a rule of thumb, a good cut off point to avoid SD diamonds is crown angle no more than 35 degrees combined with a pavillion angle of 40.8 degrees.

As to best crown and pavillion combos, there are many potentially great measurements, best thing is to use the HCA and Idealscope images to see which works best. For example, a shallower crown angle along with a slightly deeper pavillion angle can produce and sock exploding effect with some. You could stick to the combos considered cherry by some PSers which are;

Crown angle - 34.4 - 34.8 degrees

Pavillion angle - 40.5- 40.9 degrees.

Bear in mind that opinions can differ with these and they also need teaming with a good depth, table and girdle thickness.
