Is a heart-shaped diamond a good choice for an engagement ring?

Yes if you want something romantic and less common than a round brilliant. Heart cuts show their shape best from the top and can look smaller face-up than a round of the same weight.

What does I clarity mean for this diamond?

I clarity is the lowest of the included grades. Inclusions are typically visible under 10x magnification and may be noticeable to the eye, especially in a larger stone.

Will the white gold band need maintenance?

14K white gold is usually rhodium plated. The plating wears over time, so expect replating every year or two to keep the bright white finish.

Can this ring be resized?

A plain 14K gold solitaire band can usually be resized by a jeweler. Heart-shaped settings can make some resizing harder, so have it done by a jeweler experienced with the setting.

Does it come with a matching wedding band?

This is a solitaire, so no band is included. A plain or diamond band in 14K white gold can be paired with it, and a curved band may fit closer to the heart setting.
