Round Brilliant 1.5 carat with 7.6mm width?

[Cking332]

Hi Everyone,

I am looking at a Round Brilliant 1.5 carat I/VS2 diamond with the following dimensions:

EGL Certificate
7.61 x 7.5 x 4.42mm
Depth: 58.5%
Table: 61%
Crown: 11%
Crown Angle: 29 degrees
Pavilion: 44.1%
Pavilion Angle: 41.5 degrees
Girdle: Very Thin to Medium Faceted
Cut: Good
Symmetry: Good
Fluorescence: None

I get an HCA of 2.1, but I'm unable to find any other diamonds at this weight with similar dimensions. It's being sold at a great price (under $7k).

Is this a rare find opportunity or a pass? Anything I should be concerned about?

Hmmm. I can’t comment on the price because there’s not enough info but here are some thoughts:

The certificate is EGL ... this lab is known for being soft on grading in the US. So take the colour and clarity grades and assume that they are really 1-2 grades lower than reported, compared to grading by GIA or AGS.

Then EGL says that cut and symmetry are only “good.” This means that there’s a chance that it’s even less than good in real life. Yikes!

Add that to an HCA of over 2 with a super shallow crown angle of 29, and I would say a big NO to this diamond.

Pass and for many reasons. Beginning with the cert, EGL is not reliable as far as color/clarity. They could be 2+ grades off. so that I/VS2 with EGL may grade as a K/I1 with GIA. Then the Cut and Symetry. you want an Excellent on Cut, Polish and Symetry.

The parameters are also not really complimentary. The reason it's so much larger than other stones you're looking at is because it's very shallow at 58.5%. The crown angle is also exceptionally low at 29 degrees/11%. It will look pancake like. You ultimately want a stone that gives some great sparkle, lots of light return and based on the parameters, it's just not likely.

i'm shocked it got a 2.1 HCA, i went and plugged the numbers in to myself to confirm. lol! Regardless, i'd pass due to all of the above. Is this a virtual stone or something a B&M store has shown you?

I will be viewing in person tomorrow, but thank you for bringing all of this to my attention. When I saw the HCA, I was very surprised and unsure if I had just happened to stumble upon a steal.

Pass 100%. This isn't a "steal" at all. It's a poorly cut stone with a cert from an untrusted lab. It's priced low because it's not good.

Much appreciated everyone, thank you for helping me work through this.

To be fair, I know which vendor this is, and I like their settings and (some of) their stones when someone is on a super tight budget (like they need a diamond for under 1K). But you aren't in that position, so I wouldn't want to see you "settle" for something that just isn't up to par.

I have nothing good to say about this stone. Flat top, large table, deep bottom half and a VT girdle = horrible cut.

Compare it to this well cut 1.5ct. notice the difference in diameter ?

The HCA is a quick and dirty rejection tool, not a selection tool. It is a great tool. It is the rare stone that can almost fool it. That is why it is a tool. Use all of your tools, including YOUR eyes. Then you will know better what YOUR eyes like...

A great stone possibly for a pendant - but no way for a ring as it will chip - thin girdle and very very shallow crown angle. It should be very bright when compared to other well cut stones but may not have much fire.
