Is this good lab diamond?

[jstorm]

Can you tell from the image of.the diamond and setting is good proportion? I don't have aset images.

 

[tyty333]

Hi @jstorm...can you post the whole copy of the report (or provide a link to the stone)?

Might want to put it on hold first.

Hi, jstorm - just from the screenshot it looks to have quite a bit of CVD graining going on.
Any links to a 360 rotational video of this one?

What is CVD graining ?

Graining of the diamond material that the finished diamond is cut and polished from since CVD is process that grows diamond rough in tiny layers upon layers upon layers.

Here's a fantastic write-up by Bryan with Whiteflash about how crystal material defects carries a lot of risk and can cause serious issues to the appearance of a diamond:

Thread 'Milky Diamonds – What Causes Transparency Issues and How to Identify Them'

Dec 2, 2024

We tend to think of diamond as a totally transparent material but that is not always the case. Sometimes diamonds are hazy and often described as looking “milky”. Diamonds can appear milky for a number of reasons. Most often the cause is related to the presence of clarity characteristics such as microscopic inclusions, but can also be the result of defects at the atomic level in the carbon lattice. Strong fluorescence, particularly in combination with light scattering inclusions, can also cause a loss of transparency resulting in the diamond having a hazy or milky appearance.

Is the cvd in the corner area?

Is the cvd in the corner area?

CVD is one of the two primary methods used to grow diamond crystal/rough.

CVD = Chemical Vapor Deposition
HPHT = High Pressure, High Temperature

HPHT is the (much more expensive) method used which attempts to replicate the way the Earth makes diamonds: high pressure and high temperature.

Thank you for the article

What sellers have you been looking at, what carat range, and what budget are you wanting to stick with?

Cavalera is reasonable price. Can you help get a good one 3 to 4 carat .I wanted the hearts arrow cut which he has some on his website. The one posted above is hearts and arrow cut.

I found a 3 carat D VVS2 HPHT with Hearts and Arrows and a fiery 40.8/35.0/54 combo that is listed at that seller for under USD$1200.
Does that fit your budget?

 

[jstorm]

Yes. Thank you. Do you a 4 carat also?

Can you send me link to the 3 carat?

 

[jstorm]

Or can you send me private email message of the link? Thank you

 

[DejaWiz]

Sorry, was an early night for us at the DejaWiz household.
I'll be on periodically throughout the day.

We dont have any private messaging capabilities on Pricescope so you and @DejaWiz sort of need to coordinate together.
He's on a fair amount so it usually works out...

 

[jstorm]

Can you both help me find a 3 to 5carat round blue lab with calavera with hearts and arrow. I see one but is it good cut proportion?

 

[jstorm]

Option 2 blue lab diamond?

 

[jstorm]

I sent 2 images of blue round lab Grown. Can you chrck if it's good cut? Hearts and arrow for both. Let me know if you find a better blue lab gown between 3 to 5carat. Thank you

Diamond 3

 

[tyty333]

I'm having a hard time reading the first two. The numbers on the 3rd one look good but we need to see an image to be
sure.

I think the very first one is good if the angles are 34/40.8.

Can you give the table/depth/crown and pavilion angles on the second stone?

Can you see if the 3 diamonds attached are good cut for blue lab diamond?

 

[MackPUK]

Diamond 3 proportions look pretty much spot on

 

[DejaWiz]

Can you see if the 3 diamonds attached are good cut for blue lab diamond?

Can you post screenshots of the first two from the face-up view (if you don't want to share grading report numbers) so that at least the cut precision can be generally assessed?

The last one appears to have some unevenness with the pavilion facets and I question the diamond crystal quality...there's a planar cloud in there along with the polka-dots of carbon specks.





If you're wanting closer to perfect, then you may want to scratch this one off of your short list.

This is such a great example of 'on paper stats don't tell the whole story' - thanks for sharing your insights with the forum Dejawiz

CORRECTION: this is one of the "Hearts and Arrows" designated diamonds ending in 650...

Ok to don't get the 650 ending. What about the other 2?

 

[jstorm]

Thank you for showing images of pla ar clouds. What about the other 2 diamond choices?
