Questions and answers

Which looks bigger, the 2 ct Pompeii3 or the 1.50 ct James Allen?
The Pompeii3. At 2 carats its round stone is roughly a third larger in face-up area than the 1.50 ct James Allen, and both are round brilliants in six-prong yellow gold solitaires.
Is the James Allen worth about $266 more?
If grading matters to you, yes. The James Allen is D color, VVS2, Ideal cut with Excellent polish and symmetry and an IGI report. The Pompeii3 is FG/VS with no stated cut grades, but it gives you half a carat more for less money.
Which is better for everyday wear?
Both use six-prong 14k gold settings, which hold the stone securely. The James Allen's stone sits higher, so it can catch on clothing more; the Pompeii3's lower-profile high-polish mounting is less exposed.
Can I get the Pompeii3 in a size other than 6.5?
The listing shows size 6.5 and says other sizes are available by phone at (847) 367-7022. The James Allen listing does not state a size, so confirm sizing with the store before ordering.
Do lab-grown diamonds last as long as mined ones?
Yes. Lab-grown diamonds have the same physical, chemical and optical properties as mined diamonds, so wear and hardness are identical. The difference between these two is grading and size, not durability.
Which has better color and clarity?
The James Allen, clearly. D color and VVS2 clarity beat FG color and VS clarity, and the James Allen also states Ideal cut, Excellent polish and Excellent symmetry.
