Explore East Coast Jewelry's collection of lab grown diamond stud earrings — real, IGI-certified diamonds grown in a laboratory and set as classic round solitaire studs in 14K white gold. Also sold as lab diamond earrings, lab created diamond earrings, and lab made diamond earrings, these stones share the same chemical, physical, and optical properties as mined diamonds, so they sparkle identically to a natural stone. Every pair is graded D–F in color and VS1–VVS in clarity — the premium, near-flawless end of the scale — and ranges from 1 carat ($800) to 10 carat ($3,500) total weight.

Why choose lab grown diamond earrings
A lab grown diamond is a real diamond — it has the same brilliance, fire, and 10-on-the-Mohs hardness as a mined stone — so it holds up beautifully to everyday wear. Because it is created in a laboratory rather than mined, it is far more affordable — typically 30–40% less than a comparable natural diamond — which means you can choose a larger carat weight or a higher color and clarity grade for the same budget. It is also inherently conflict-free, and set in solid 14K white gold, making these studs an easy, timeless gift for an anniversary, graduation, or milestone birthday.

Frequently asked questions
What are lab grown diamond earrings?
They are earrings set with real diamonds grown in a laboratory instead of mined from the earth. Lab grown diamonds are optically, chemically, and physically identical to mined diamonds. Ours are round solitaire studs in 14K white gold, graded D–F color and VS1–VVS clarity.
Are lab grown diamond earrings worth it?
Yes. You get the same beauty, sparkle, and hardness as a natural diamond for roughly 30–40% less, and every stone is IGI certified. In 2025–2026 they remain one of the best values in fine jewelry, which is why buyers can afford a bigger carat weight or a higher D–F / VVS grade.
How much do lab grown diamond earrings cost?
In this collection prices run from $800 for a 1 ct pair to $3,500 for a 10 ct pair, all in 14K white gold. See the carat & price guide above for each weight.

All of our lab grown diamond studs are D–F in color (colorless to near-colorless) and VS1–VVS in clarity (eye-clean), placing them at the premium, near-colorless and near-flawless end of the IGI grading scale. Each stone is IGI certified with its own report.

Studs, hoops, and drops each have their place, but a round brilliant solitaire stud is the most classic and versatile choice — it suits everyday wear and any outfit. That is the style we specialize in.
