Are "spready" diamonds good or bad?

[dar7]

If the HCA scores well is it a good buy if the diamond offers excellent spread?

 

[Gypsy]

Depends on the angles.

Post the table, depth, pavilion and crown angles.

 

[Gypsy]

Also the HCA is a rejection tool. Not a selection tool.

Can you get an idealscope image of the stone?

6.82x6.86 for a round 1.15 carat? It scored a 1.3 on the HCA tool. Too good to be true?

It's a 60/60 with a low crown. I wouldn't want a crown of lower than 33.5 for a 60/60. Ideally 34% to 35.5%

You need idealscopes for 60/60 stones.

Thank you Gypsy!

There are lots of 60/60's out there and they are discounted because so few of them are performers.

So you can find a nice 60/60 with a good crown/pavilion angle combo for a good price usually.

What are you looking for: color/clarity/size/budget?

Don't buy a flat top stone...

Thanks guys. I love this community here. I've learned SO much. I've been burned a couple times on bad diamonds and through some good money after bad. But I am here so I will never do that again. I'm here learning and researching before a spend money on another diamond. My goal is to replace the current center stone in my double halo. It's a .91 E color EGL so it's more life a G/H I'm told and it's SI1, very good but that's more like a fair cut. It goes dark in lots of lighting and drives me nuts. I don't even wear the ring right now. If I"m going to replace it I'd like to go up a bit in size as well. Maybe 1.11 give or take? I'm ok with going as low as an H color as long as it is bright and sparkly. I like bright diamonds. That I've learned about myself. I'd like to stay under 7k, is that possible?

My fiance and I have 2 60/60 diamonds. Both are good performers. You just have to ask for an idealscope and ASET image to be sure. Her diamond is 1.7 carats but faces up closer to 1.8-1.85 due to the spread.

 

[dar7]

I meant EGL cut is very good but the HCA has it at fair.

 

[D&T]

don't knock out diamonds in the 2 range... I've seen too many good diamonds to totally reject diamonds in the 2 range. Further evaluation is needed like this

I have a diamond that is cut with ideal proportions. It is a performer. But I wish it had a bigger spread with the same performance.

Do not buy or consider an EGL stone.

GIA or AGS only.

EGL is so unreliable there are lawsuits pending over them. And rapnet has banned them. Any jeweler offering you an EGL stone is a rat leaving from a sinking ship.

 

[Gypsy]

EGL is banned from Rapnet. And people are suing over how inaccurate the lap reports are.

Indeed the EGL is banned from Rapnet. However a supplier I know still has about 4 thousand EGL stones in inventory and still quotes the price as 'back' from rap.
Rap prices are pretty much the standard among the trade.

I don't think I'd like to be him!


re: the original question, I think it was Wink that posted up the results of an informal experiment regarding Ideal cut vs shallow cut stones - IIRC either Wink's wife or one of his trusty elves wore one earring with an Ideal cut and one earring with a shallow cut, and just wore them 'as usual' without any particular cleaning regime. I believe the end results were that the 'dirty' shallow cut was favoured by those surveyed, rather than the Ideal cut?

I've owned a couple of similar proportions except shallower pav angle. That stone won't have the same look as a modern H&A superideal. But if the symmetry is decent and the diamond doesn't go dark close-up, it might still be a decent performer. There are a lot of older RB diamonds out there that have similar proportions and can be good performers and a good value if priced right. Most have more brilliance than fire. They can look big and bright, however.
