Our take on the Round Cut 3-Prong Martini Lab Grown Diamond Stud Earrings

These are a pair of round-cut lab-grown diamond studs in a 3-prong martini-style basket setting, made in solid 14K gold with screw-backs. Each stone is hand-selected at D-F color and VVS+ clarity, and the stated total carat weight covers the pair, so each ear holds about half. The martini basket sits close to the ear, which keeps the look low-profile compared with four-prong settings that stand taller. Screw-backs hold more securely than push-backs, a plus for everyday wear and for anyone who has lost an earring before. Lab-grown stones give the same look as mined diamonds at a lower cost, though resale value is lower.

Cons

Questions and answers

Is the carat weight per earring or for the pair?
It is the total for the pair. Each earring holds about half of the stated weight, so a 1 ct total means roughly 0.5 ct per ear.
What does D-F color and VVS+ clarity mean?
D-F is the top colorless range on the GIA scale, and VVS+ means very very slightly included or better. Both are high grades, so the stones look clean to the eye.
Are these real diamonds?
They are lab-grown diamonds, chemically and optically the same as mined diamonds, just grown in a lab. They are not cubic zirconia or moissanite.
Will screw-backs stay on during sleep or sport?
Screw-backs are among the most secure backs and are much harder to knock loose than push-backs. Still, take them off for contact sports and swimming.
How do these compare with four-prong studs?
The three-prong martini basket sits flatter against the ear and shows more of the stone from the side. Four-prong settings hold the stone edge more fully but stand taller.
Can I wear them every day?
Yes. Solid 14K gold and screw-backs suit daily wear, and the low martini setting keeps them from catching on hair and clothing.
