Is a lab grown diamond a real diamond?

Yes. It has the same carbon crystal structure, hardness and sparkle as a mined diamond. The difference is origin, and it is graded by the same labs.

Will the oval stone look bigger than a round one?

Usually yes. An oval of the same carat weight spreads across more of the finger, so it reads larger while sitting lower in profile.

No. Resale value is much lower than for a mined diamond, so treat it as a purchase to wear, not an investment.

Yes, 14K gold is durable enough for daily wear. Check the prongs and setting periodically, since solitaire settings leave the stone exposed.

A plain 14K yellow gold band or a thin diamond band sits flush against most solitaire settings. Confirm the band width matches before buying.

Clean with warm water, mild soap and a soft brush, and store it separately to avoid scratches. Have a jeweler check the prongs once a year.
