Best lab diamond earrings on Amazon
For most buyers the best lab diamond earrings on Amazon are round studs of 1 to 4 carats total weight (half to 2 carats each) in solid 14k gold with screw backs, with IGI reports for both stones. Lab-grown diamond is real diamond, so studs this size cost a fraction of mined ones. Read "ctw" carefully: 2 ctw means two 1 carat stones, not two 2 carat stones.
How we pick: We list a pair only when its own listing says lab-grown diamond and gives the total carat weight and the gold karat, and the style matches the pick. Every option had an Amazon price and was in stock when we checked on 17 October 2026. Grades and certificates on a listing are the seller’s claims.

Frequently Asked Questions
What does 2 ctw mean on diamond earrings?
"ctw" is carat total weight: the weight of every diamond in the pair added together. 2 ctw studs are two stones of about 1 carat each.
Do lab diamond earrings look different from mined ones?
No. They are the same material with the same sparkle; telling them apart takes laboratory instruments.
