Are these real diamonds?

Yes. They are lab-grown diamonds, which have the same carbon crystal structure as mined diamonds but are made in a lab. They are not cubic zirconia or moissanite.

How big are they on the ear?

The pair totals 1/4 carat, so each earring is about 1/8 carat. That reads as a small, subtle stud, closer to a dot than a statement piece.

Will the sterling silver tarnish?

Yes, sterling silver tarnishes with exposure to air and skin oils. Store them in a closed box and polish with a silver cloth; avoid wearing them in the shower or pool.

Are lab-grown diamonds worth it?

For everyday wear, yes: you get a real diamond look for much less than a mined stone. For resale or investment, no, because lab-grown stones hold little resale value.

What comes in the box?

Expect the earrings with friction or screw backs in a Zales jewelry box. Confirm the back style on the product page, since small studs can be lost with loose backs.

Our take on the Zales 1/4 CT. T.W. Lab-Grown Diamond Solitaire Earrings in Sterling Silver

These are single-stone stud earrings from Zales: a 1/4 carat total weight of round lab-grown diamonds set in sterling silver. The solitaire stud is the simplest diamond earring shape, so the look depends almost entirely on stone quality and setting. Lab-grown stones cost less than mined ones of the same size, and sterling silver keeps the price low, but silver is softer than white gold and will tarnish over time.
