Is a 6 carat oval lab diamond too big for everyday wear?

It is a statement size. The stone sits tall above the finger, so it catches on sleeves and knits and is easier to knock. Many owners wear a large oval for occasions and a plain band for daily tasks.

What does E-F color and VVS2 clarity mean here?

E-F is near colorless, so the stone looks white in most lighting. VVS2 means very very slightly included, with inclusions hard to see even under magnification. Both are high grades for a lab grown diamond.

Does the IGI report cover the accent diamonds?

The IGI grading report is for the center diamond. Accent stones of this size are usually not individually certified.

How does an oval compare with a round brilliant of the same carat?

An oval faces up larger per carat because it is elongated, and it looks bigger on the finger. A round brilliant returns more light and hides inclusions better, while ovals can show a darker bow-tie band across the middle.

Will a lab grown diamond hold its value?

No. Lab grown diamonds trade at a fraction of natural diamond resale and prices have fallen as production has grown. Buy it for the look and the size, not as an investment.

What should I check about the setting and band?

Ask about band width and the height of the head, since a 6 carat stone needs a sturdy setting. Confirm the ring can be resized and that the accent stones are secure.
