Is a lab grown diamond a real diamond?

Yes. It is chemically and physically a diamond, grown in a lab rather than mined. It has the same hardness and brilliance, and IGI grades it the same way.

How does a princess cut compare with a round solitaire?

A princess cut is square with pointed corners and gives a sharper, more angular sparkle. A round brilliant throws more even light return but looks smaller for the same carat weight.

Will the white gold stay white?

10K white gold is alloyed to a white tone and usually rhodium plated. The plating wears over time, so expect re-plating every year or two with daily wear.

Can the ring be resized?

A plain solitaire band can usually be resized by a jeweler. Sizing down or up a little is routine; large changes on a diamond-set band are harder.

What should I check on the IGI certificate?

Look at the carat weight, color and clarity grades, the cut grade, and the measurements. Confirm the certificate number matches the stone and the report is from IGI.

Is a lab grown stone a good choice for an engagement ring?

It gives you a large, certified stone for much less than a mined one, which suits many buyers. The catch is resale value, which is low for lab grown diamonds.
