Is a marquise diamond a good choice for an engagement ring?

Yes, if you like an elongated shape. A marquise spreads wide across the finger for its carat weight, so it looks larger than a round of the same weight. The trade-off is two pointed ends that need a setting that guards them.

What is the Cigar setting?

It is Vrai's low-profile solitaire setting, with the diamond held close to the band. That keeps the ring from catching on clothing and protects the stone better than a high, open setting.

Is the diamond lab-grown?

Vrai builds its business on lab-grown diamonds, which have the same physical and optical properties as mined stones. They cost less than comparable mined diamonds but generally resell for less.

Can I wear a wedding band with it?

A plain or slim diamond band sits flush against most solitaire settings. Because the Cigar setting is low, check the band's height so the two rings sit evenly.

How should I care for 18K white gold?

White gold is rhodium-plated to get its bright white look, and that plating wears off over years. A jeweler can re-plate it, and gentle cleaning with soap and water keeps the diamond bright.
