Can you tell me if this is a good choice?
Round Lab Created Diamond
Shop Beautiful, Affordable, and 100% real diamond engagement rings. Clean Origin Lab Created diamonds are identical to mined diamonds having the same chemical, physical and optical properties as their mined counterparts.
Best (and safest) bet is to stick with a super ideal cut.
The dimensions will fall into the following ranges:
Overall depth: 59.5-62.0%
Table width: 53-58%
Crown Angle: 34.0-35.0°
Pavilion Angle: 40.6-40.9°
Star Facet Percentage: 48-55%
Lower Half Percentage: 76-80%
Girdle: Thin, Medium, or Slightly Thick
Polish: Excellent/Ideal
Symmetry: Excellent/Ideal
Here's a handy chart that the creator of the HCA made to help you target a diamond with good and complementing table width, crown angle, and pavilion angle combinations:
Start with looking at VS2 clarity and F or E color which are still colorless like D, but a potential for massive savings or getting a bigger and better diamond for the same price of a D.
SI1 would be fine for weights below 2 maybe even 2.5 carat, as long as they are eye clean.
Avoid clouds and twinning wisps as inclusions (there are some others to outright avoid as well, but these two are usually encountered more). If they are present in the VS or better clarity grades, then they are likely insignificant enough to not inhibit transparency and light performance, but perform due diligence. In the SI or worse grades, it is very possible that they would/could be a predominant defect (if present and stated on the certificate) and moderately to severely impact light performance.
HPHT and CVD are the two methods to grow lab diamonds.
In a nutshell:
High Pressure High Temperature (my personal preference) mimics the conditions that form diamonds in the Earth.
CVD (Chemical Vapor Deposition) grows a diamond tiny layer by tiny layer until the rough is adequately sized for the intended final cut and polished product(s). Many CVD diamonds are post-growth treated, and sometimes that treatment is (ironically) HPHT.
Both methods have their own unique advantages, disadvantages, nuances, and characteristics...much like a natural diamond depending on which specific mine it comes out of.
$3000-3200 will land you around a 1.45 F VS2 or around a 1.6 F SI1 and look just as colorless as an E or D no matter the material and style of the setting.

Thanks so much for this information. It was very helpful. Here is another one:
Lab-Created 1.26 Carat round diamond
This 1.26 carat Lab-Created round diamond F color vs1 clarity has Ideal proportions and a diamond grading report from IGI
To widen your search I would recommend using another search beyond just James Allen, unless you are committed to purchasing from them. You will have a wider range of stones to review. I used Rare Carat
