Pic''s... What do you think?

[Stephan]

A friend found this diamond online...
What do you think about this diamond?
I have to ask you before to answer him.

The price is $1,864.00.

Just by a quick glance at it, I don't really like the J color or the strong fluorescence. Fluorescence seems to be a tricky thing and can sometimes make the stones look milky in sunlight. I'd consider stones with a strong fluorescence only if they don't exhibit the milkiness.

It also seems to be missing the total depth which is an important figure. Or maybe I just don't see it.

I guess $1,800 isn't that much money for a .80ct but there are probably much better purchases to be had elsewhere.

You can find the total depth this way:
(6.00 + 6.03) / 2 = 6.015
3.62 / 6.015 = 0.6018
=> depth = 60.2%
J color is not the problem for this friend (for me it isn't a problem too), of course the fluorescence can be a problem but we have to take a look at this stone first.
I saw a lot of strong-fluorescent diamonds, and not all these diamonds are milky...
My question is how do you find the pictures and how do you find the proportions?

Looks like a good deal to me on a very nicely cut diamond.

HRD is great too!
May I ask you where did you find it?

 

[Choon]

Hi ... well the price seems ok for a 0.80cts ...as for the Fluorsence, i say its a good thing that it comes with the fluor....however for HRD, there is a ? on the J thingy.

Anyway for the price its ok.

Hello Stephan,

I have no problem with the accuracy of HRD, and as far as we can judge the proportions, they are reasonable. Although with a crown height of 15.5 % and a table of 59 %, you should estimate the crown angle somewhere around 37°, which is quite steep (calculation from the top of my head, Diamcalc will give you a more exact angle).

Price does not seem outrageous either.

I however have two other problems:

One, the date of the cert (2000) and two, the fact that the diamond is sealed.

Knowing that the seller is in Antwerp, a stone with such an old cert should have been sold by now, and that leads me to suspect why it is sealed. Maybe, something is wrong with the stone, and one cannot inspect it as long as the stone is in its sealed package.

It could be milky, because of its strong fluorescence. Despite the proportions mentioned, it could still perform badly on light return and sparkle. Or indeed, it has a lucky cert (possible with any lab), and the real colour and/or clarity are much lower.

What is important, is whether the stone can be inspected before the sale is final.

Live long,

Paul

Hi all, and thank you!

Sorry Giangi, I was not online when you asked your question.
Yes, it is www.gendiat.com.

Yes Paul, you are right, so we have to take a look at this stone first to be sure. But I thought that a 37 degrees crown is not so bad with a 40 degrees pavilion?

Paul, I hope you will soon find a rough diamond to cut my 3ct! I am very exited!

 

[Mara]

Wow a 37 crown and a 40 pav angle?




Plugged that into the HCA and WOW!




A FIC with EX EX EX EX and a score of 1.0 EX. Pretty nice.




I would definitely take a 2nd look and as Paul suggested, check the stone out first and I would also get an independent opinion on it. If the stone is not milky, that strong fluor will be a huge benefit when it comes to the J color...should face up whiter!




If it looks good, then it may be a winner!

 

[Stephan]

Yes, Mara, if the stone is not milky, it can be a winner.
And the price seems nice too!
