Are lab-grown diamonds real diamonds?

Yes. They are chemically and optically identical to mined diamonds, just grown in a lab. They are not cubic zirconia or moissanite.

How big do 1 ct total weight studs look?

Each earring holds about 0.5 ct, roughly 4 mm across in a princess cut. That is a noticeable but modest everyday size.

Will the screwbacks stay on during sleep or sport?

Screwbacks are among the most secure backs and resist slipping off. Most owners still remove them for sleep and heavy activity.

Do these earrings hold resale value?

Very little. Lab-grown diamonds resell for a fraction of their price, so buy these for wearing, not as an investment.

What is included with the earrings?

Expect the pair in a KAY box with the lab-grown diamond certification paperwork. Confirm the certificate at purchase.

How do these compare with round lab-grown studs?

Princess cuts show a squarer face and sharper sparkle, while round brilliants hide inclusions better and have no corners to chip. Both come in similar carat weights and gold settings.

About the KAY Lab-Grown Diamonds Certified Princess-Cut Solitaire Stud Earrings 1 ct tw 14K Yellow Gold

These are 1 ct total weight princess-cut lab-grown diamond solitaire studs in 14K yellow gold, set in four-prong settings with screwback posts. The stones are graded F color and SI1–SI2 clarity, so they read white and eye-clean in a square cut that throws more flash than a round brilliant of the same size. The pair suits shoppers who want a diamond look without mined-diamond pricing, though the screwbacks and sharp corners take some getting used to.
