Help finding LG Diamond

[Kasel]

I’ve been perusing threads, reading articles and after deciding I would prefer a lab diamond over natural I’ve realized I need some help. I’ve read up on the differences between CVD and HPHT and I‘m leaning toward HPHT. My concern is blue nuance but I’ve read that if I stay around D-F this may not be a concern. I could also go with CVD but get scared off when I read post-growth treatment on the cert.

Looking for 2.5 -2.7 ct, D-F , VS2-higher, budget 10,000- 12,000 for stone. I’m interested in vendors that offer trade up to hopefully have some “equity” if I decide to upgrade in the future. I realize that the few that do this are often higher $. Is that worth it?
TIA for any help or ideas you have! I’m learning so much from this site.

James Allen is about your only source to get a quality HPHT LGD with an upgrade program.

If any of these jump out at you, then contact them and put them on hold ASAP so someone else doesn't buy them before you make a decision.

This one will lean towards more fire:

Lab-Created 2.54 Carat round diamond

This True Hearts TM diamond, 2.54 carat Lab-Created F color vs2 clarity has ideal proportions and a diamond grading report from IGI

This one will be balanced between brilliance and fire:

Lab-Created 2.53 Carat round diamond

This 2.53 carat Lab-Created round diamond E color vs2 clarity has Ideal proportions and a diamond grading report from IGI

This one will also be balanced, and maybe lean slightly towards brilliance because of the 40.9° PA:

Lab-Created 2.50 Carat round diamond

This True Hearts TM diamond, 2.5 carat Lab-Created E color vs2 clarity has ideal proportions and a diamond grading report from IGI

What does HPHT type II mean?

What does HPHT type II mean?

The growth method isHigh Pressure High Temperature, which mimics the conditions that the Earth makes diamonds.
Type II is the classification of diamond.

Type II has two subsets:
IIa - no nitrogen traces.
IIb - boron traces are present, giving the diamond a very faint blue twinge. Also electrically conductive.

For IIb diamonds in the G and worse color grades, IGI will usually notate "blue nuance" or "faint blue" on the grading report, such as this one:

Lab-Created 1.57 Carat round diamond

This True Hearts TM diamond, 1.57 carat Lab-Created G color vs2 clarity has ideal proportions and a diamond grading report from IGI

For colorless range diamonds, the notation will not be disclosed/present, like this one:

Lab-Created 1.72 Carat round diamond

This True Hearts TM diamond, 1.72 carat Lab-Created F color vvs1 clarity has ideal proportions and a diamond grading report from IGI

There are a few threads floating around with pictures of blue nuance diamonds...to some (including me), they look pretty cool. I wonder if it's something that I could tolerate over the long term, though. Maybe one day I'll get a small 0.4-0.5ct blue nuance diamond to make a men's ring for myself. Shrug.

Great explanation and these are great examples! Do you know why they don’t report blue nuance in the colorless range?

It almost makes me more inclined to go to G. I started using Diamond Screener blue detector and it helps a little but it doesn’t filter out CVD so it takes some patience.

That’s very cool!

Probably a human judgment call based on hue and saturation, I'd assume.
