Are these real diamonds?

They are lab-grown diamonds, chemically and optically the same as mined diamonds, grown from a diamond seed. They are not cubic zirconia or moissanite.

What does F/VS1 mean?

F is the top colorless grade and VS1 means very slightly included, with flaws hard to see under magnification. To the naked eye the stones look clean and white.

How big are the stones?

Each stone is about 6.6mm across, and the pair totals 2.00 carats, so roughly 1.00 carat per ear.

Are the backs secure?

They use twist-on (screw) fittings, which hold firmly and suit everyday wear. Expect a few extra seconds to fasten them compared with push backs.

Do they come with certification?

The pair is described as certified. Ask the seller for the grading report so you can check the color, clarity and carat figures yourself.

How should I care for 18K white gold?

Clean with mild soap and water and a soft brush, and store them separately. White gold is rhodium-plated, so it may need re-plating every year or two to keep its bright finish.
