Need help with AGS rating. Looking for GF's perfect ring!

[thebigjdoe]

I have been researching about diamonds and settings for my girlfriend's ER, and need a little clarification. I found this diamond, which seems to be a good deal at a little under 7k. I am sort of a noob so I don't get why 1. its cheaper than others with it's raiting, and 2. why it is a vs2 with very little inclusions....I would think VS1 would be more fitting (again, what the heck do I know)

Also, what is a "Natural"? In the symbols it says Feather, Crystal, Natural. What exactly does this mean, and is that why it's cheaper than I would think it should be. I have requested Ideal Scope and ASET images, and should have those tomorrow.

I have already received help from some awesome members here, and and ALMOST ready to to post a new topic with some narrowed down options, but wan't all the knowledge I can handle before I'm ready to purchase. Yes, I have issues lol.

Once again, thanks to all the experts for their help.

AGS number and vendor were removed so anyone can feel free to chime in. Thanks!!!

where are you looking?

the pavilion angle is 0.1 over the magic 41.0 point, the depth is very slightly deep, the girdle is undesirable going from thin to slightly thick (more risk of chipping) and your cutlet is painted.

crystal is the worst type of inclusion in my opinion, but at VS2 should not be noticeable unless its right under the table.

what is its tonal colour? if its brown/grey instead of yellow, this may also explain why its at a slightl discount to other Hvs2 you are looking at in 1 carat range.

ok i hear what you're sayin. I thought a pointed culet was standard. Not sure about the brown/grey thing. I am probably just going to take a few of my previous recommendations, maybe add one that i find, and create a thread and let the experts decide.

My girlfriend likes this setting from B2C Jewels:

http://www.b2cjewels.com/Round/1/8478/Diamond-Accent-Settings/Round-Halo-Engagement-Ring-14K-White-Gold.aspx

So was thinking If i could find a good diamond there, it would work out. She would like a slight gap between the stone and the halo so I was thinking by getting both the setting and the stone from them it would work out better as they could set it how we wanted it.

Will sleep on it again for another night, and go from there. I am the worst decision maker on the planet, so ya

* Goes back to previous thread and looks again at recommendations.

A "natural" isn't an inclusion. It's an unpolished area of rough that's left on the stone, in the girdle area. It will look like tool marks, like saw or rasp or file marks or something similar under magnification. Depending where it is relative to the arrows, and what setting you choose, it may be prongable. Depending on how large it it, it may or may not be obvious to the naked eye. More of a blemish, but that stone has some variability in the girdle thickness, so probably the cutter made some decisions to retain weight at 1ctor above to get more money for the stone.

The one you linked to is graded AGS 000 so it's a good looking stone and it's HCA score will be 2 or less. But it's less than the preferred 6.5mm for 1ct. If a stone is deeper, it may face up a bit smaller, if shallow it may face up larger. Shallower than probably 60% (iirc) may have head obstruction probs (looks "dark" up close but fine at farther distance is a sometimes called a "pendant stone."

The grade setting inclusion is listed first. It's "feather" for that stone, so you need to know where the feather is and whether or not it's likely to be a durability risk in a ring. I can't see the inclusions plot this computer I am using.

Yah, I was thinking the feather might be an issue. It is on the left side almost at the edge, so it makes me think it would make it weaker than if one was near the center. Here is another image, but yah, I may just look elsewhere for sanity sake.

Looks amazing.

The light performance and ASET look pretty darn good. The only knock on it is it's a pretty deep diamond (63%) so it will face up more like a .90-.95 carat diamond that's cut to a 61-61.5% depth. If you're fine with the face-up size though, it looks like a great performer. The crown angle is a little shallow at 34, but it complements the deeper pavillion angle of 41.1, so it should be fine and give off alot of bright white light (Brilliance) compared to colored light (fire).

6.4mm is acceptable for a 1 ct. Most excellent (non-H&A ideal cut) stones .9-.95 are about 6.15mm to 6.30mm. Usually only see 6.4mm on a .95ish stone if it has a large table, shallow crown/steep pa combo.

What's the price on this one?

This is $7005, or $6795 wire transfer. Yah I'm still debating, not sure if I want to pull the trigger yet. Still searching for that perfect stone, or....perfect for the value. Probably by early June will buy something, so will keep my eye out.

I'm wondering, do I send the setting to the person I buy the diamond from, or send the diamond to the person I buy the setting from? (assuming I get them from different vendors)

edit: On a side note I put this through the HCA, and oddly it is over 2. I was under the impression that an AGS 000 would be under two so there is no point in checking, but this one did score over 2.

Also, with a feather so close to the girdle, is this a higher risk stone of cracking or chipping? Thanks guys and gals, you people rock

Re: Need help with AGS rating. Looking for GF's perfect rin

You don't run the HCA score on AGS 000 but the HCA score is a predictor for light performance, the AGS score actually measures light performance (guess which one is better?). Think of it like a credit score - the credit score won't let me know if you will default on a loan, just how likely you are. The AGS will actually tell me if you're a defaulter or an on-time payer. Gypsy has a somewhat more visceral analogy I like about women's measurements, but I'll leave it at that

The higher HCA score is coming from the 63.1% depth and the slightly steep pavillion angle of 41.1. If you re-ran it with a pavillion angle of 41, you'd get a score of 1.6. The good news is looking at your ASET the angles compliment each other well to produce a 0 light performance grade, using a much more complex system than the HCA does.

Ok, cool, i remember reading gypsy saying that you DONT HCA AGS diamonds haha, but I couldn't help myself lol. good to know and thanks for the explanation (sometimes it takes a few to get through my thick skull hahaaa, us men right....)
