Is a lab-grown diamond a real diamond?

Yes. Lab-grown diamonds have the same carbon crystal structure and hardness as mined diamonds. They are grown in a lab rather than mined, and a jeweler can tell them apart only with specialized equipment.

How does 10K gold compare with 14K?

10K gold is 41.7% pure gold; 14K is 58.3%. 10K is harder and more scratch-resistant but looks slightly less rich in color, and white 10K gold may need rhodium re-plating over time.

Can the rings be sized?

A plain band can usually be sized, but a three-stone ring with diamonds along the band is harder and sometimes impossible to resize without rebuilding it. Order the right size, and ask about sizing policy before buying.

Will the wedding band sit flush with the engagement ring?

The set is designed as a matched pair, so the band should sit close to the engagement ring. If you plan to wear them separately, check the band's curve against the engagement ring's profile.

How should I care for the set?

Clean with warm water, mild soap and a soft brush, and have the prongs checked once a year. Take the rings off for gym sessions, cleaning and swimming.
