I found a stone on Mondera.com that looked good on the Holloway (0.5 TIC) and that seemed like a fair price. But what are all these other cuts? I definitely want the maximum in all 3 brilliance, scint, and fire..

1. A diamond that displays intense white light reflecting from almost every angle, and displays a smaller amount of colored light.

Or

2. A diamond that displays intense colored light dancing from almost every angle, and displays a smaller amount of white light.

I'm asking this simple question because you can't really acheive the best of both worlds. You can reach a cross section, but you can't have maximum colored and white light return in the same diamond. When one goes up, the other tends to come down.

I suppose I would trade off the color for the white, but I would still like a lot of shine (I know that doesn't say much).

Now the cutters will jump up and down

Many of the H&A diamonds have very high white light return, and lower colored light return. The Eightstar has very high colored light return, and lower white light return.

The above is a general rule, not a hard fact that never changes.

Think of a crystal prism, in your eye do you admire the colors or the white light? Only you know exactly what you like.

Not all AGS000 are heart and arrow type diamonds. Don't think that they are, but still very beautiful diamonds in the top few percent of all the diamonds cut.

Best of luck in your hunt!

Eightstar is different from all other H&A diamonds because it's cut to achieve special Firescope image.

However, only you can decide whether these exclusive features are worth something to you. Ideal cut diamond with HCA=0.5 you've found at Mondera is a great stone.

0.906 ct
VS1/G
Crown: 15.2% (34.5deg)
Pavil: 42.4% (40.5deg)
culet: 0.7%
table: 55.7%
total: 60.8%
girdle: 0.5 - 1.2
price: $5262

But,I checked a few places and found a .91 AGS000 G VS1 at under 5k.

The price they are asking is very fair and I would never tell you to worry about the price of something you seem to like. Go for it!

and what do you think of the size onto a 6-prong? Are there 6-prong solitares that are not "Tiffany style" or is that the standard?

I think you'll find it answers all your concerns.

It has been adopted by over 800 members of National Association of Jewelry Appraisers (NAJA).

1A class is much more strict than AGS0, i.e. if the diamond is AGS0 it doesn't mean it's 1A class. (see www.gemappraisers.com/chrt1.htm )

Here is the Q-Factor chart from www.cutstudy.com/cut with different cut grades put together by Sibelius. As you can see 1A AGA grade (white rectangle) is the most narrow and close to Tolkowski

You know the rules: give at least some education first, please...

The diamond you will see every day.

When I called them, if memory serves me correctly a few months ago, I think they said that scintillation is the most perceivable fire in a diamond, and thus, many customers find Diamond "X" with the same exact 4 c's as Diamond "Y" to be preferable depending on the scintillation readings. See Jonathon at GoodoldGold's postings on PriceScope or DimaondTalk sites for his comments based on customers' responses.

Apparently, white and color light aren't near as important.

And scintillation is very inaccurate as No One has been able to produce scientific proof that they can measure it. The Bscope counts pixels of colored light and white light, and the difference is where they come up with scintillation. Not the true meaning of scintillation and not from all distances(only a few).

Maybe Johnathan would like to comment on this and a few other questions I have.

The best thing is to compare with your own eyes and see what you like.....it is your money.

I guess now i can get my mind off that one, and get a D-F color stone.. :P

The lesson is, when you find the diamond you love go for it quickly, it may not be around very long.
