Indented Natural on an otherwise perfect diamond

[Horace]

Hi guys,

I will need your advice on this diamond that I am considering to purchase. It is a 1.01 Carat, G color, VS1, GIA 3X, medi fluor round diamond with a good HCA cutting grade (1.7).

The GIA report: https://www.gia.edu/report-check?reportno=1275451020

The video of this diamond: https://v360.in/movie/84_R66141

The ONLY issue is that it has an indented natural on it. Perhaps that is why its price is about 700$ cheaper than other diamonds of similar quality.

In your opinion, is this diamond worth buying for?

Much appreciated!

Horace

An indented natural is just a part of the diamond rough that was left in place and is below the polished surface of the stone. It isn’t a defect per se but something entirely natural that was just left in place by the cutter (just like a natural inclusion which is just a part of the rough stone that is left unpolished on the surface).

What I’m not liking is that it is slightly deep at 62.9% and the CA is a little high. Given that GIA rounds the crown angle on its reports to the nearest 0.5°, it could be anywhere from 34.76° to 35.25°.

I would be requesting Idealscope and/or ASET images of this stone to determine if it’s light performance is decent or not if you are considering purchasing this one.

Thank you BMFANG,

I would for sure ask for additional info.

would you consider cavity as an big issue then? It is listed in the GIA report.

I agree with @bmfang.

Cavities are rarely an issue for VS1 diamond. A cavity is a 'hole' in the diamond surface. It can collect oil and dirt. In SI1 and below stones, I would avoid them as they are large enough to be problematic especially if located on the table. This cavity is along the girdle, so any dirt should not impair the performance. Just don't have the setter try to cover it with a prong. Not only will that cover the tips of the arrows, it will make getting it clean near impossible.

The cavity is pavilion side right on the girdle. It can be a magnet for oil, grease and dirt, meaning increased cleaning of the ring to ensure the stone performs best. As @rockysalamander said, you would not want the stone to be set with prongs covering over it to aid in cleaning.

I would ordinarily try to avoid stones with cavities in them. There are plenty of stones in the market.

I wouldn't buy a stone with a cavity...more of a "mind issue"...
